Today I put another 639 rounds through gun number 2. 500 of WinClean and the other 139 were my 147 reloads. That brings the total to just over 3k with no issues at all. Today the 639 rounds where fired in just under an hour and a half. Let's just say she got a little hot. Like, be careful where you touch the gun or it will blister you (not as bad as an M&P, some of you know what I am talking about).
So far so good. Hopefully I will hit 4K in this gun before the week is out.
Cheers
