45 GAP in 625?

[zeeew]

Hello all

Anyone shot the 45 GAP in a 625? Is this cartridge too short for decent accuracy? I figure it may get slightly faster reloads.

I have been shooting 45 gap in my 625 for about two years now. I use them in competition. they work great. I use a 200 gr. extreme plated bullet. with 4.5 grs. of WST

I have no experience here, but if you mean factory loaded cartridges, S&W could surely give you an answer - as to safety. Does the GAP round operate at substantially higher pressure? If so, accuracy may not be the main concern. Just a thought, in case you haven't considered it. If you call them, I would be interested to hear what they say.

45 GAP operates at 45 ACP +P pressures (23,000 PSI).

since the .45 ACP case headspaces on the
case mouth edge, with or without full moon clips I would guess the .45 GAP if used with
FUll MOon clips is prevented from going into
the chamber by the FM clips so the firing pin
can hit the primer. I'd like to know from the
poster who said he's been using .45 GAP for 2 years 1. What kind of Competition? 2. Any problem with light primer hits? which begs the
question is it a stock length firing pin or the
C S lengthened one?

About the accuracy the bullet would have to make what a 3mm jump from chamber diameter to the tighter area of the cylinder then the foricing cone, just more things to upset and get a bit of wobble eh?

Isn't it kinda spendy ?

The 45Gap has been used by several in ICORE and IDPA competitions. Those that I have seen shoot extremely well and accuracy was not the issue with them. if you reload, primer strikes are also not an issue.

 

[Revolver King]

I shoot IDPA, IPSC, ICORE and the PSA shootout in Hershey every year. I have never had a light strike and I am using a 625 4" with IL and stock firing pin. I use only federal primers for all revolver loads. as far as moon clips I like the rimz moon clips used for the older model 25s.Have a great day.

 

[zeeew]

Oops, left out that 45 GAP would be with full moon clips. Also would be reloads after enough brass was collected.
How do the rimz clips do, will they hold loaded cartridges securely enough? Never used them or even seen in person.

Everyone talks about the jump, hell they have shot 38's in the 357 since the 30's. They have shot the 32 S&W in the 32 long since 1896 to now. I shoot 32 long in a 32 mag in BULLSEYE and it will kick you inports ass in a match. The jump isn't going to hurt it, they shoot 38 colt all the time in the 627. I'm getting a cylinder cut on a 25 in 45 colt cut for moons clips so I can shoot the colt, schofield,acp, and gap in it.

Fit of .45 GAP in the steel moonclips is very loose and not practical for speedloading. At least that is my experience with Speer brass. I think the serious competitors have special moonclips made. And while you're at it, don't forget the very aggressive chamber chamfers and 5 lb. DA trigger pull that fires only perfectly seated Federal Primers. In my opinion none of this is worth the trouble and aggravation.

I use the RIMZ exclusively in my .45 ACP revolvers as well as my 610 and 646. Never had a failure with them.

 

[BlindJustice]

STill haven't heard the answer as to why one
would use .45 GAP in the 625 ?

RIMZ moon clips - I've got 5 anybody want em
let me know, cartridges fall out of the things, and sometimes the expaended cartridge was left in the chamber because of the poor grip of the RIMZ. That's my experience, if they work for y'all good for you.

My curiosity is really piqued by this thread. Based on the testimonials by several of you .45 GAP works just fine in a 625 chambered for .45 ACP. But, what advantage is there in using GAP vs. ACP? Obviously, there must be some advantage or people wouldn't do it, but what is it?

 

[scott625b]

BJ:
With all the complaints you have about RIMZ, did you ever tell them or send the product back? I'm sure they would like to know if a defective part left the factory. You have made some extreme claims about their product, I'm sure they would like to know what is wrong.

As I am sure most of you know, the .45 GAP was developed as a way to offer the traditional .45 cartridge within the dimensions of existing 9mm/.40 autoloaders so that a total re-engineering (and larger gun and grip) could be avoided, which is usually required due to the .45 ACP's longer OAL. The solution was to shorten the case to GAP length and design loadings that could deliver the ballistics of the ACP with safe pressures.

When we are talking about 625's and the GAP, I don't think there is any significant advantage over the ACP unless your particular guns shoots it more accurately. I have two 625's that are much more accurate with the auto-rim than ACP, maybe the GAP will work like that in some guns?

uhmm... not.

My M25-2, the acp cases sit to far in the chamber to fire without moon clips.

Kinda partly sometimes. My 3 ACP 625s will all fire without clips, as will my chopped 1917.

But then I have to poke the cases out of the cylinder with a stick.

It's generally thought that shorter cases load and unload with less difficulty. The problem of cases caught under the ejector star is pretty much eliminated by the moon clip itself, regardless of case length. I personally don't think that the shorter GAP case makes much difference in speed or reliability, but YMMV.

Based on some previous work with .455 Webley case lengths in .45 Colt chambers, there may be"an accuracy problem from tipping bullets in the longer unsupported space before the chamber throats from .45 GAP in moonclipped .45 Colt revolvers.
