you cant have a p30l a glock and a beretta in the same list... because then your choice comes down to one question . . metal or plastic,
if you take out the beretta, between the glock and the p30l . , the p30l will prolly fit your hand or anyones hand for that matter better than the glock. its got different grips with it, its a da/sa gun unless your getting the LEM that isnt out yet.
then theres the glock .consistant shooting, (everytime you squeeze the trigger its the same.) unlike the p30l.
the glock is a $hitkicker, work horse that is tougher than anything really out there. the design is so simple my 4 yr old nephew can fieldstrip it, clean it, change trigger bar, and replace the striker before bert and ernie sing him a song.
go with the glock. shoot it, then go buy the p30l because your going to wonder what its like to not shoot a toy gun. and then when you feel its time to step up to the metal guns look at the beretta, but check out the sig first.
have a good day..
