I have two Glocks, a 21 and 30. Also a Gemtech Blackside, and as barrels of both weapons are threaded (LWD, a superb company), have the ability to utilize my CCW, with either, AND use the Blackside, if necessary. The G30 is for every day carriage, while maintaining the G21 for "serious social difficulties," for when the the wheels fall off. Commonality of ammo and magazines, as well as M6Xs and Blackhawk fanny packs, is a definite plus. Now, to "the" question... I've pretty much relegated the 21 to situations that may or not be around my home for self defense, as in the case of civil disorder, like cities experienced in the time from the 1960s to the present. I found myself in the middle of a riot, when I got back from SE Asia in the early 1970s, and it was not a pleasant thing to experience. I've seen weapon's sights (like Aimpoint's Micro T-1) that can be mounted on a polymer(?) frame, attached to the weapon, above the slide, allowing usage of the sights(Ameriglo suppressor sights) as well, and allowing the rail below the slide to be still utilized for laser/light combos(as in M6X). Couple this with the Blackside, and 14 of Winchester PDX1, and you have a formidable piece of gear. If I go this route, making a civilian's special purpose weapon, I lose the ability for it to be concealable. I'm not King Kong, and though my clothes look like they're from Omar the tent maker, even my 48Short sport coats won't cover it easily... Now, would it be smart to assemble now, if ever, or go another route? What say you? Assemble and store, or go back to the drawing board? WHEN TSHTF, I'll have to E&E. My AO would NOT be survivable. Taking this into account, I eagerly await your answers and ideas... OldArcher, out... Wanna kill these ads? We can help!
