I grew up shooting revolvers, especially GP100's, but this is my first with moon clips. I have two other 10mm's but they are both autos. I own a Wiley Clapp 3" GP100 and I inherited a 4" GP 100 that I gave away. Both of those are in 357 and the 10mm by far has the best trigger. Maybe because it is the newest or maybe because it is a Lipsey's although I believe the Wiley Clapp was a Lipsey's also. Every GP100 I have ever fired did nothing but improve with time so I imagine the 10mm's trigger will get even better. I can't emphasize enough how nice the double actions trigger is on it. Fired what I think in today's market amounts to a small fortune in 10mm. 200 rounds of Blazer Brass 180's, 50 rounds of aluminum 200gr Blazer and 20 rounds of Corbon 135's. I know I have some DoubleTap JHP somewhere but I couldn't find them. Had to take several breaks to reload moon clips but more importantly let the revolver cool down. It got really hot after around 50 rounds. I would hate to shoot that amount of ammo without the demooning tool. It was a real time and finger saver. The revolver functioned flawlessly. When I took my time in single action it would shoot to the point of aim. Didn't bind at all regardless of how hot it got. The group in the picture was fired single action from a poor standing position at 8.5 yards in an indoor range with terrible lighting. Had the obligatory flyer and I could easily see the revolver was more accurate then what I capable of. Also, had a real problem seeing the front site in their. I probably need to touch it up with something. All of the 10mm ammo functioned flawlessly and all extracted flawlessly. Used a little more force on the aluminum casings as expected but nothing that really amounted to something out of the usual. I previously put Hogue's on it because the wood grips it came with didn't fit my hand or the gun well. I wouldn't even want to try an extended session with the factory grips. I do think the revolver is more pleasant to shoot than my S&W 1076 or Kimber Stainless Target II but I guess that's subjective. I ordered the TK Custom moon clips from Amazon and tried them with 40 S&W. Out of the 18 rounds of Winchester Silvertips I loaded up, only 9 fired. The rest had light primer strikes. Didn't bother messing around with it because the GP100 is known not to function well with 40's. Also, a pin on the rear site backed out and I put some Loctite on it when I got home. Realized when I had finished two things that I seem to forget from time to time. I tend to shoot the heaviest bullets the best, whether it is a 200gr 10mm, 147gr 9mm or 170gr 30-30. Not sure why but it always seems to work that way. Also, revolvers like this, 10mm, 357Mag, 44Mag, etc., are not meant for extended shooting sessions by your average shooter with full power loads. They are kind of like deer rifles that you site in, make sure they shoot well with your ammo of choice and then stored until needed.
