Moon clips for gp100 match champion

Recommended Posts

Anybody have first hand experience  with s&w 646 moon clips being used in a 10mm gp100?

 

Seems like the aftermarket hasn't gotten around to that ruger yet .

I realize this is an old post but just recently bought a GP-100 10mm and thought I would share my moonclip experience in case it helps someone else.

I purchased a pack of 10 TK moonclips for the GP 100 10mm Match Champion and found the fit was too loose with just about any brass except for Win headstamp. Federal was also loose but would remain in moonclip from holder on belt to cylinder during reload . R-P and Starline brass would not stay in moonclip during reload as I would have at least one cartridge fall out. With Win brass the TK moonclips work great and this combination is my choice for matches . I am using Ruger moonclips to shoot the non-Win headstamp ammo I have already loaded for my 646.

I'd totally missed the 10mm GP100 Match Champion. I suppose it also works with .40 brass (???)

edit:

Oh, the moonclips are different thickness:

I had missed this too . Probably explains my other issue with the 10mm GP-100.

That's strange.  Both TK & Ruger brand 10mm moonclips are the same thickness - .032.

I failed to mention in my post about my moonclip experience with my GP-100 has been with 40 S&W . Although I have 300 pieces of new Starline 10mm Auto brass all my shooting has been with 40 S&W reloads. With my S&W 610 I can use the same moonclips with 40 S&W and 10mm with no problems however with the Ruger GP-100 moonclips there is a headspace problem using .032" moonclips (and I have experienced light strikes using Federal primers with 40 S&W brass with .032" moonclips) . TK is making a moonclip .040" just for 40 S&W that will hopefully take care of my light strikes . I have ordered some to try and if they work I might just be able to go with a lighter hammer spring. I had high hopes of using this pistol in IDPA for something different as I usually shoot speedloader fed S&W revolvers but the light strikes have been problematic.

Please let us know how it goes.

My TK .040" 40 S&W moon clips arrived today and I was able to give them a try. First off I found that R-P headstamp brass fit loose but would not fall out when reloading but the Win brass still fit the best . The extra thickness of this moonclip seems to have solved my primer light strikes and was even able to go back to a 9 lb. hammer spring with no misfires . So, in all these moonclips were everything I had hoped for and plan to be shooting the 10mm gp-100 in my next IDPA match just for something different.
