GP 100 10mm Project

[gsokk]

Always been a fan of three inch guns. Surprised the GP 100 in 10mm did not take off / sell more. It’s up for debate but I see the 10mm in this configuration as 357 magnum performance with the option of a heavier bullet. My friend ran this gun with Buffalo Bores 220 grain outdoorsman load through his chronograph and was getting consistently 665 foot pounds of energy at the muzzle. If the barrel was not ported high 690 to 700 foot pounds would be a close guess.

six shots with an outdoorsman load would make a nice trail gun, self defense 10mm ammo or 40 cal in moon clips  for self defense, fairly easy to carry on the hip, I carried it a few times in a fancy pack, while not my first choice for CC I do see plenty of application for this gun. Consider all the 40 cals in circulation and the 10mm fans out there, expected to see more of these out there.

while I’ve done crazier projects, I do like this one, custom grips, porting, night sites, and a very nice action job. Very enjoyable package.

Great SD revolver. I attempted to purchase a 3" 10 in a GP but they had been snatched up. I have a 3" GP adjustable sighted 357 that is a very nice revolver. Proper leather they are not that hard to carry.

I've never seen a Gemini Customs I didn't like, and these two are no exception.

I agree, moon clips and a 10mm make for a solid all around package. Not sure if 10mm magnum is ok in a GP (I'd guess it is) but if so that'd be a nice option as well. Could presumably shoot 10mm or magnum since you headspace off the moon clip, with the caveat standard 10mm can't be fired outside a clip.

What I never quite wrapped my head around is where the money goes for a Gemini gun. Most here are familiar with the work and hours involved in full-built single actions, but for DA that retain the factory cylinder and barrel I don't know what all is done for that price point.

I shoot a GP-100 M/C in 10mm in my USPSA competition. Love it!
