A pic of my Glock 22 with Lone Wolf comp:

In fact, I don't believe ANY external modifications other than grip tape and sights are allowed if you want to shoot in Production (at least in USPSA).

Thanks for the answers/opinions guys. No national matches for me in the near future, so I think I'd be fine Ken

Is the Glock 21SF considered just a variant of the 21, or a new model. If the latter, then I think it would not be allowed in USPSA Limited class since it hasn't been in production for over a year (correct me if I'm wrong). If the former, then it would be allowed. Anyone know for sure? TIA, Ken
