Got my G20 back from Mark Housel at L&M Precision and I must say he did an amazing job! I fired 150 rds. of Underwood 180 TMJs this past weekend and it ran like a top! His bore sight was dead on also, I was consistently hitting a steel plate at 110 yds with it. It's my hog gun and I hope to get out this weekend and rack up some pigs, which I'm more than confident this gun can handle at 30-40 yds.
Gun info: Gen 4 G20 (box stock) RMR Adj. LED 6.5 MOA dot and Ameriglo suppressor night sights. I also purchased a L&M slide cover plate if I ever decide to remove the RMR and it looks great. If anyone is looking to RMR a pistol I can't recommend L&M precision enough.
