Last year I picked up a 9VE as part of my "hope springs eternal" program. Although I am mostly a wheelgunner, I was shooting 1911s and BHPs in the early 60s; still do.

I took quite a liking to the Sigma, though, and it shot very well for me--MUCH better than I had ever done with Glocks and SIGs. I attribute that to the grip shape and the DA revolver-like trigger. All the ammo through the gun--about 500 rounds--has been my reloads. I have had a few failures to fire, which I attribute to deeply recessed primers in IVI brass. More disturbingly I had several failures to feed in which the rounds jammed into the bottom of the feed ramp. No particular reason that I could find. NO mods to the gun whatsoever. I keep detailed records on these things. All the ammo was loaded on a single stage press, loaded with Rem. 115 gr. JHPs, and gauged. I have loaded for my other semiautos for decades, and load 5.56, 7.62, and .30-06 for semiauto rifles. The upshot was that I was getting a failure about every 85 rounds. The BHP feeds and fires everything monotonously to include the above rounds that the Sigma didn't.

The days are gone when I had cases of factory ammo available and could pretty well eliminate ammunition as a problem area when testing guns. But since I don't have that option anymore we're down to home brew for 99% of what I shoot. I hoard a small quantity of +P+ 9mm and some standard loads I duplicate in the above handloads. I suppose I could pick up a few boxes of white box FMJs to experiment with but that's not a real world choice and no indication of what the pistol will do with serious loads.

Some years ago I had a much worse experience with a Ruger P97, which all the "experts" said was the perfect gun. This one, at least, was possessed by demons. After a year and 1200 plus rounds, not to mention trips to the factory, Ruger took it back, destroyed it, and sent me another NIB...which I promptly put on consignment without even firing it.

I didn't "need" the Sigma when I bought it. I still like the gun (even though it's just a 9mm) and I'm just disappointed. Like the P97, I shot it well and was rather fond of it.

After 50 years of shooting duty pistols, I'm inclined to think that, like Chief Dan George, "Sometimes the magic works, and sometimes it doesn't."

The upshot is that RELIABILITY is primary with me. I know that Murphy is always lurking, but he seems to avoid revolvers and my 1911s and BHPs are downright boring guns.

Boring is good.

Gremlins can sneak into any pistol. I've got 7,000+ rounds through one of my SW40GVE's with only 2 failures of any kind, both with handloads and both with an extremely dirty gun. The other SW40GVE has about 3,000 rounds through it and it's never had a failure, of any kind.

Malfunctions are inherent in less-than-perfect machines. Guns fit that mold.
 
Amen to that. Some of my best guns have unlikely origins. I spent half my life sneering at Model 10 Smiths. I don't do that anymore.
 
I use the LEE FCD on all my auto ammo. No burps yet. 9mm, .40 in a Sigma 40VE, and .45ACP in various 1911's and a 625-3. Not that I think a revolver would jam, just adding it as no firing pin issues or extraction sticking. If you read how to set the FCD like the directions say to I think most guys wouldn't have such an issue with it. If you find it swaging your bullets check the carbide inside diameter. It is only supposed to kiss the brass if it is set right. If you have an oversized chamber and need an oversized bullet to fit it then either have Lee custom make your die or punch out the carbide ring. The taper crimp it sets has been VERY jam free for me even with 200 grain SWC's in my 1991A1's. They are bone stock and will spit them out. YMMV though as usual.
 
total agreement on the FCD from Lee...best thing since sliced bread, and not just for autos...perfection for older stuff such as 32WCF, 38WCF, and 44WCF....first and foremost, as a handloader with closing in on four decades of experience, is that if it feeds factory ammo and doesn't feed yours, it is a loading problem and not a gun problem.
 
I use an RCBS taper crimp die and check the loaded rounds in both a gauge and by dropping each round into the barrel of the stripped pistol--what would that have to do with a round's nose jammed into the bottom of the feed ramp? I don't see a chambering issue here.

The Lee die might indeed be a good idea, but I don't see a chambering issue here. A mag issue, perhaps, but not chambering issue. And new Mec-Gar mags for the BHP are half the price of Sigma mags.

This sort of predictable, if infrequent malfunctioning for no discernible reason is just an annoyance in a non-duty plinker. In a duty gun or a parachute it would be somewhat more serious.

After fifty years of fooling with these things all I know is that some things work and some others don't always work quite as well. It's just that semiauto anythings choke at a higher frequency. Some do it a lot less and some almost never.

I still think the magic theory has some validity.
 
mine did the round jammed into the bottom of the feedramp with exactly one brand, the 115grJHP Winwhite....feeds the 148s from same brand perfectly...also will note it probably was doing this with the least fired mag...i truly believe the hicap mag springs need time to take a bit of a set so they are not overly powerful and refusing to allow the round to nose up and out of the magazine....in short, no magic but a mag issue...also, again, if, and a big if, it is feeding factory stuff but not handloads, it is obviously because the handloads are not to the factory spec...and the gun is supposed to feed factory spec first, and everything else second.

As for magic, i have owned numerous guns, quite a few full blown customs (not a package job, a CUSTOM) of both revolver and self-loading...this Sigma has been one of the most astoundingly reliable handguns I have ever owned...curiously, one of the other most reliable self-loaders i have ever owned and still own is a 1960 Beretta Minx in .22 Short, Italian made...that little baby has never malfunctioned in decades, and as an FYI will shoot through fresh 1/2" plywood and a gallon jug of water behind it at 7yds.

Thanks for the comments. I probably would not have bothered posting any of this on another site, and expected a vigorous defense of the dark horse, fairly beloved Sigma. That's all to the good. Might I point out that many of the comments use the word "if", and "I believe" frequently. That's not a problem as I do it a lot myself. I did it a lot when I wrote reports, particularly when I had to come to some sort of conclusion with insufficient evidence and no prospect of more. That comes into play a lot with philosophy and particularly religion, and that's appropriate.

I'm a lot less comfortable with that level of certainty when it comes to guns. If the thing works as reliably as the sunrise I'm happy to accept it and even take some credit if I can get away with it. If not, we're all too often forced to trouble shoot as best we can--which can mean a lot of speculation. A lot of the time we come up with an insight and reduce the problem, and learn something we didn't know. But not each and every time. My experience with the P-97 where we took it to the extreme proved that sometimes we just don't get to know WHAT was going on. Presumably God does--but He's not saying.

As a range officer, supervising experienced officers with quality, well maintained weapons with fresh factory ammo, I would see a certain number of malfunctions. Not a lot, but even a few are disturbing and not confidence-raising. It was frustrating (and embarassing) to examine the malfunction, clear my throat, shift my feet, and admit that I really didn't know what caused it--and carry on. I suspect the medical profession does the same thing to some extent...

If there's a gunsmithing school in the afterlife I want to go to it and find out all the answers we don't get here.
 
new member here. I have a sw9ve and love it. anyone try to make it full auto. I know its illegal if you dont have the right paperwork and stuff, butsound fun to do.

thanks
 
there is no paperwork you can get for making a new full-auto, unless dealer or law enforcement....you will also get fairly few replies on a thread hijack, especially one where you ask folk to post of illegal activity on servers which can be traced....
 
I had some fail to feed issue when my Sigma 9 was new and then I read a post on here about taking apart and cleaning the magazines before the first use. Haven't had a fail to feed since. I don't use reloads but just whatever is the cheapest at the range that day.

That's a really ludicrous question. Why on earth would anyone want a full auto siggy? Never mind, I'd rather not know.
