Just watched all the vids again. IMO two techs must be learned for defense/match and hunting. The best thing I ever did to improve my handgun shooting was buying a Crosman CO2 .177 pistol with the best match for a Berretta M9: Sighted in @25 from a rest (hunting) with a full cylinder I began to do some things as it expired.
Not a big fan of this airsoft shit all the hell over the place--"JERRY!--HELLO!!!"
That is all:
