Honestly, you really don’t feel it if it is, I have several Glock pistols and this one doesn’t feel any fatter than a Gen4 G19. It shoots really well, extremely accurate with cheap 115 gr. at 10-15 yards. I will take it out farther today but I expect it will hold up at distance as well. If I run across a G17 version I will buy it for sure.Very interesting! I will look up some reviews. It looks thick in the grip.
