Well, I finally got this resolved. LOVE. LOVE the gun. Evidently there was a design change and the pin that was being sold on the website was different than the pin that I broke. Took awhile, but Kahr customer service actually did okay in the end. I just needed to rant, I suppose. I tried to purchase a t40 as they are going, going... My rapist retailer wanted too much $$ for it though. So, I just bought a used one, should be here Friday. I have not read completely through the thread, but intend to now. Thanks for your responses...
I can remove the slide lock pin very easily with my fingers, I just had not lined up the slide correctly. I swear the directions are incorrect that came with the gun. I read all the forums and got the impression on a new K40 the pin is "tricky" sometimes. So I whacked it and snapola, RATS. Honestly, I ran 500 rounds through the gun so far without one problem, flawless performance. I am now hooked.
According to the instructions, I was to line up the second larger cutout with the pin. So, I stuck a dowel in the chamber, lined up the cutout exactly with the pin, flipped the gun over and whacked it with a punch. Snapped like a carrot. The outside of the slide lock was still caught on the slide, so I broke the pin where it attaches to the finger part of the slide stop. Not sure on terminology. I tried everything else before resorting to the Flintstone method. Lesson learned. Thanks for your reply.
Another “glad it worked out” from me.
muggsy: Let's face it, being shot by a .380 will ruin anyone's day.
Interesting. By "broke like a carrot" I envisioned something different. For future reference, I would suggest using firm pressure with a hard, but non-marring object, once the slide is lined up right. Some guns will become easier and not require a tool to help, others will always remain tight, in my experience.
On the used T40, I suggest you consider replacing the recoil spring before shooting much and if the gun does not look well-broken-in, then lube it pretty well for a while. I almost always replace recoil springs on used semi autos I buy, since I have no idea how many rounds have been through the gun before.
