Can anyone tell me why some Glocks have a tapered slide and some don't? Is it just for looks or is there some technical reason for the difference? Both my G26 and G36 have tapered slide (at the muzzle) but my G21SF does not and I don't think my G19 does either. Personally I like the tapered muzzle. It holsters a little easier. Can one of you Glock experts enlighten me?
