I found that my ultrasonic case cleaner does a great job cleaning my sigma... Question, could you dry the frame and slide in a cool ( 170f) oven?

You're pushing your luck unless the oven is precisely controlled.
Some of the polymers used in firearms start to soften over 200 F, and there is a cotton damper inside some of the springs.

What in heavens name are you doing to your poor Sigma that it requres such drastic cleaning? I've Sigmas that have been shot many thousands of times by dozens of shooter, and all I do to the frame assembly is spray it out with CRC silicone and wipe out the excess--it dries quickly and leaves just a touch of dry silicone, which is all it needs for lubrication.

The better question is, why would you want to do this? You are going way overboard on the cleaning.

here is why.. The extractor broke a couple months ago. I sent it to one of S&W's service center for repair. At that time they did something to the trigger ( invoice said"replace extractor, adjust trigger ), which really smoothed it out, but it immediately started getting light strikes. I sent it back and they replaced the striker. Now it seems that if i don't keep it really clean it starts getting light strikes at about 500 rounds, which is about 1-2 weeks of shooting for me.....Before the original problem, i rarely did any more than field strip and spray it down with rem oil one a month or so
 
There is something wrong with the gun then, and it's not cleanliness. No gun should need to be ultrasonically cleaned and baked in an oven every 500 rounds to remain reliable.

Well, that's what I would think also.... but what can I do. that's what it takes to keep it shooting reliably....
 
If you do that much shooting, have you thought about upgrading to a better gun? A Sigma is about as low as you can go in the handgun world. How about a nice M&P? ;)
 
Don't put the assembled gun into the ultrasonic bath, break it down and clean the parts. When done, blow it dry with compressed air, followed by a spritz of REM Oil, Ballistol, etc. (WD-40 can gum up with time).

If you have access to a laboratory drying oven, OK, but don't do it at home. The oven has two temperatures - air and radiation. The first is controlled, the latter is 1200-1800 deg F (the color of the element). More than one tupperware frame has been broiled in a kitchen. It makes for a good You-tube hit.
 
I agree with having them fix the light strikes. I'm sure after two sessions having it repaired, thus not having it, isn't very pleasant, but..still, it should not be having light strikes. We have heard about less-than good quality work from service centers- maybe send it to S&W this time.
 
I'm not familiar with ultrasonic cleaning solutions, but you can buy canned compressed air (if you don't have a compressor) and gently blow out the moisture. You can follow up by using spray silicone. I use a silicone spray from the auto store (can't remember the brand name) it evaporates somewhat quickly. Then lubricate it per S&W instruction manual. After each range trip I clean my pistols and lubricate them
according to manufacturers instructions (they clean easier IMO). If that doesn't do the trick send it back to S&W.
You didn't say what the problem is when you just clean and lube to S&W manual or how many rounds you fire at each range session, or how many range sessions between cleanings.

My plan was to pre-heat the oven to 170 or whatever the lowest setting is, then turn the oven off, and then put the parts in
 
When I clean my duty M&P 45, I just strip it and throw the parts in a piping hot sink full of Dawn (remember, it takes grease out of your way)...break out a tooth brush and scrub away. The heat of the water helps evaporate what's left after drying. I usually only give it this treatment once a month before inspection.
 
if you have to go to those extremes there is something wrong with your gun or the ammo you are using. i have about 750 rds through my sigma with only basic cleaning with zero problems

750 rounds? sometimes i shoot that much in two weeks, maybe that is the difference. For reference, i have shot 1080 rounds so far this month.

I guess your rich then after you factor in range time and cost of ammo, wow over a 1000rds in one month do you want a cookie? If you want to toss your gun in an oven have at it.

No, I reload. ( costs me about 15.00 per hundred ) The range I use charges me 150 a year for a family membership.
 
so you bought a sub $300 gun and are running over 1000rds of reloads a month in it and wondering why your extractor is breaking and you are seeing light strikes?

YES, I AM WODERING. It may be inexpensive, but if S&W is going to put their name on it, I would expect it to work. For the price , I would not expect a fancy finish, or a lot of extras, or a nice smooth trigger, but I would expect it to SHOOT !
BTW, I am a fan of S&W, my wife and I have several of their revolvers , We have Smith revolvers that are 30 yrs old, that get shot more than the sigma, and still function flawlessly.

B. HANDLOADED OR RELOADED AMMUNITION
!! WARNING !!
• Never use non-standard, reloaded or "handloaded"
ammunition which has not been subjected to internal
ballistic pressure testing. Reloaded or handloaded
ammunition, may have many manufacturing and quality
variables (such as the type and amount of gun powder).
 
Jeez, are you serious? Of course, all manufactures put that in there.. in case you are too stupid to reload properly, and blow up a gun. For, your information, I have shot a lot of white-box winchesters, and had the same problems...
