Suppressors 45 GAP in Kimber Custom II

[ArcticLight]

Anyone had any issues shooting GAP ammo out of a Kimber CUstom II?

I had heard the extractor could be an issue on the Custom 2 and the GAP appears to be a higher velocity ACP round.


Thanks,

GAP ammo is not the same as ACP ammo, the cases themselves are shorter.

I would not suggest shooting GAP ammo in something that is chambered for ACP ammo.

ah did not know that, read a few online articles that suggested it could be used.

45GAP was an attempt to fit a 45 caliber cartridge into a G17/22 small frame auto. The case is shorter and head spaces differently.

YIKES seriously? Like 858 said the GAP was designed by Glock so they could get 45ACP performance in the same sized frame as a 9mm or 40s&w. Straight walled pistol cartridges headspace off the rim of the case. With the case itself being shorter than an ACP round I dont see how it would work.

Now it wouldnt surprise me if someone was making mags and an aftermarket barrel to shoot the GAP stuff out of a 1911.

But I figure if you are going to tote a 1911, then why not either tote something that has proven itself like ACP or something hotter like 10mm since its not going to change pistol size any at all.

If you are wanting higher velocity than 45ACP

You can always load 45 super

Or if you want another level try the 460 roland.

GAP ammo pressures supposedly run slightly higher than standard .45ACP, but still lower than +P. The SAAMI spec is 23K.

Also, I've read GAP ammo uses a specific primer designed to operate in extreme temp variations with no change in pressures. Don't know about the propellent.

Oh yeah forgot about that ... the GAP uses a small pistol primer instead of a large like ACP does
