If I were to shoot a smaller version of a full size pistol (Glock 27/Glock 22, Para P12/P14, H&K P2000/2000SK) would it be a violation of the rules to use the larger mags in the smaller gun? They would stick out some but I don't know if this would be considered a modification or prohibited replacement part. It would save me from carrying a bunch of extra mags. Thanks.

IT IS NOT ALLOWED.

Magazines can only be loaded with six rounds by rule.So number of magazines required will depend on number needed, i.e.match 3 would require 4 magazines each loaded with 6 rounds to equal 24 rounds fired.

10/4 on that J.P. just thinking that I can tote less mags to and from the match itself (i.e. 6-8 Glock 17 mags rather than 6-8 Glock 17 and 6-8 Glock 26)
