I have a question about how tight the round is suppose to fit in the chamber... I own a G20, and I just purchased a Lone Wolf 10mm to 40s&w Conversion barrel. When I looked at them side by side, the Glock chamber seemed bigger (10mm barrel diameter wider than .40 barrel). With the barrels removed from the weapon, I then dropped a 10mm round in the 10mm barrel and it "wiggles" a little bit. The LW .40 barrel hold the .40 cal round tight. Is this normal? Should I be concerned with the Glock 10mm barrel? Do other G20 owners have the same "wiggle" with a round in the Glock 10mm barrel? Feedback greatly appreciated. Thanks.
