Hey guys, new KS7 owner here. Not new to KT though. I have a 3 digit serial number P32, had a couple P11's (including a stainless one), a PF9, and still have a PMR30. I just grabbed a KS7 at my local police supply store. Not really a steal on it, but they had it in stock. A buddy at work grabbed one as well. Initial range sessions have been positive. I have a bit over 100 rounds through it so far. One failure to extract, but it was an old round and I don't think my buddy racked it hard enough. It cleared when I tried it. I've used mixed low brass game loads, high brass 00 buck and slugs, and Aguila minis in both slug and shot. No issues other than that one sticky round. I read the article on smoothing the KS7 out and need to look closer at that. The biggest thing I noticed is a sharp protrusion when loading shells. I think its the shell stop?? Not totally sure of the nomenclature of the part. My buddy and I had to watch how we loaded or we'd jab our thumb on it. Need to figure out exactly what that part is in relation to the article before I start smoothing anything. Also read some stuff here on the "Gen 2" and how KT says there's no real Gen2 but they do upgrade things if they come in for repair. Any way to tell what I have? In theory the shop just got these in a few weeks ago, so it *should* be whatever the latest version is. Other than maybe smoothing things out, I'm not looking at doing much to this one. Maybe a sling mount, and possibly a light. Any other "must have" upgrades though in you experiences? I've been reading a bit trying to catch up an what is worth looking for.
