To each their own, if you want a modded Glock buy one if you dont then shoot a stock Glock or whatever else floats your baot. Personally I like modified stuff, my motorcycles are modified, my pickup is modified, my guns are modified etc etc. Not only do I like customizing stuff, I like working on guns and changing out parts, simply taking it apart to clean it doesnt seem to be enough I always have to tinker with stuff...
When I go to the range and see someone shooting a stock Glock I dont question why they would do such a thing, I just do my thing....And personally I own 2 fully modded ZEV Glock (19/17) and a 21 that has pretty much everything they make for it, they dont make slides yet otherwise Id buy it.....I also own a totally stock 19 and 17 also, and I never shoot them because I much prefer to shoot my modded ones...
Anyways about the guns, I originally wanted SAI, but found them a pain to deal with. Was getting too complicated and a really long wait, they also would only sell me a complete gun, were as ZEV sold me parts and complete gun.
I used IRUNGUNS to import all my stuff from ZEV, if you really want a SAI I suggest you do the same as I am pretty sure no one in Canada will have a SAI. No one did when I was looking less then a year ago anyways
I have had people question reliability in an emergency situation, well first of all there is no conceal and carry in Canada, all my guns are range guns, if it were to malfunction or break at the range Id just put it back in the case take it home and fix it. If there was ever a situation that I actually "needed" to use a gun, I have a few stock ones to choose from in that situation....So being a range only sport shooter I dont get the "oh but you made it less reliable" hating
