I'd like to buy a 9 mm Glock that is as concealable as possible. Limiting factor is that the gun has to be longer than 190 mm (7.49") or taller than 140 mm (5.52"). Anything that is permanently attached to the gun (for example muzzle brake attached with red Loctite) counts. What I have in mind is Glock 43 with longer barrel, possibly with a compensator / muzzle brake (I'll just use the word comp from now on). I have considered comp because barrel that long would, for some reason, feel fragile. And I don't think anyone is making Glock 43 barrels that'd be long enough? Glock 43 is 159 mm (6.26") long, so I'd need one that is 32 mm (1.26") longer than "original". Easiest way of making a gun longer is to equip it with a longer barrel, right So, original barrel is 86 mm (3.39") long, and I'd need one that is 118 mm (4.65") long. Does that king of barrel exist? Or then I go another route with pros and cons. Buy threaded barrel and quip it with a comp. That'd easily make the gun long enough, but then I'd most likely have to mess with the recoil spring (and possibly with some other internals as well?). And cleaning a Glock with permanently attached comp.. does not sound too nice What are your thoughts on this?
