OK, so for dedicated range guns (gens 1-4), I've heard that a lot of guys install lighter trigger return springs - along w/ aftermarket ( or factory *-*) connectors. Many would concur, that's a bad idea for a carry piece. Seems I've also heard that for carry, some guys have found an advantage to running a factory Glock NY spring (as opposed to a basic factory Glock spring) - w/ a factory Glock *-* connector. I am well aware that many are adamantly opposed to making ANY mods to the factory trigger on a carry piece, & I take NO ISSUE WHAT SO EVER w/ that viewpoint, but for those that have tried different NY spring combinations on your carry piece, I'd like to hear your thoughts - based on experience. Advantages? Dis-advantages? Safer carry - w/ a more controllable break? Big friggin' waste of time? Or what? Thanks in advance!
