For you guys that are shooting the EAA P Match Pro 10mm, can you tell me what the grip diameter is, or compare it to another firearms grip radius?  I'm thinking about buying one to hunt with, but I'm concerned the grip may be too large for me.  I've tried the Glock 20, and it just won't work for me, but there are no stores local to me that has the Match Pro, or any Witness for that matter in stock for me to try.  Thank you.

I don't have one, so I can't provide you the exact information you have requested.

I do have a Glock 20 Gen 3 SF and I have two steel Witness guns, a standard full-size and an Elite Match.  The steel Witness full size frame is markedly smaller than the Glock SF frame.  My understanding is that the P-Match is smaller still than the steel guns.

I can measure them tonight.

Thank you sir!

I measured my Glock 20 Gen 3 SF, my Glock 29 (original release...Gen 2?) and my Witness full-size steel.  I measued them three ways (four on the witness)

1.  Front-strap to back strap right below the trigger guard, shortest distance I could get.  Noted as F-B.
2.  Backstrap to trigger face (B-T), again, the shortest distance I could find.  On the Witness this was measured DA and SA.  I do have an aftermarket trigger though.
3.  Circumference (C), below the trigger guard, smallest value.  I used pipe cleaners, twisted them down tight, then snipped them off, laid them straight and measured them.

Gun Make/Model	Front Strap to Back	Back to Trigger	Circumference
Glock 29	2.140	2.890	5.890
Glock 20	2.050	2.870	5.790
Witness FS	1.950	3.100/2.700	5.450

The only place, as you can, where the witness is not smaller is the DA trigger reach.  and I think it would be shorter with the stock trigger.

Thank you, much appreciate your time!  Good info there, now I just need to get one ordered and on its way.

THere seems to be no shortage of them on gunbroker right now.

This seems to be the cheapest one:

Got one on the way, should be here toward the end of the week.  Now, since I plan on full power 10mm loads should I get an XP recoil spring?  Seems like I read somewhere that ES, and SD numbers were improved by a stiffer spring.  Who, where, and what lb. rating should I get?  Thank you.
