Kahr P9 Slide issues

[Budgetguy]

I have owned this Kahr P-9 for several years and had the grip cutdown to accept the MK series magazines. Still using the original recoil spring and have fired less than 1000 rounds (all factory standard pressure 115 gr) through it. Lately, while cleaning I noticed the "slight notch" developing on the slide. Has anyone had any experience with this?

Thanks.

I don't have a Kahr, but have heard they are good pistols.
Are you talking about the " little" nick in front of the slide release?
If you are, looks like the slide release hit it a few times.
I'd keep an eye on it and if it got bigger send it back to Kahr and have them look at it.( wouldn't hurt to call Kahr and talk to someone there) Are you useing +p or+p+, hot loads? Always been told that using hot loads can and will beat a pistol up.
Know this doesn't help much.

Thanks. I've only used standard pressure 9mm, Federal and Winchester factory 115 grain. A month or so ago, I started using Winchester Ranger 147 grain and ran less than a hundred rounds through the Kahr (only had two boxes). This gun has spent the last two years sitting in the safe and I can't recall if the "nick" was there from the beginning or just recently. I'll send a note to Kahr and order a new recoil spring as well.

Any compact with that many rounds needs a new recoil spring. Kahr springs are only seven bucks. I made the mistake of running some Gold Dot 124+P through my E-9 with a seriously weak spring. I had a broken slide stop to show for it. I called Kahr and they were awesome! Even after I told them what happened they sent me a new slide stop at no charge. I replaced the spring and have put many rounds down range since with no problems.
I would think about replacing the recoil springs every 750 or so rounds but before It got to 1000.
Springs are cheap.
