So far the only problems I've had with mine seem to be Mag related.

Really? The supplied ACT mag worked very well, so I bought two more. I also bought two of the new Wilson Combat ETM 8rd mags. All function just fine. I did have a slide "not locking back" problem and suspected an out-of-spec slide stop. Ivan at Armscor sent me another one for free and it's been fine ever since.

Yes there seems to be some problems with the Act mags that come with some of the pistols from what I'm hearing. I don't know maybe the quality is not the same with the mags that you can purchase from ACT. This would not suprise me even a little bit. I was told to try the Wilson,CMC,or the Springfield mags. Maybe it's just me but the spring pressure in the supplied ACT mag seems a bit on the weak side and once a few rounds have been emptied out of it,it doesn't want to feed properly which in turn sets off the slide lock. Looks to me like the bullet is hitting the slide lock on the inside as it tries to feed. There was a little burr on the end of it though that I have since removed with some very fine emory paper. The rounds seem to be sloppy inside the mag. We'll see what happens after I get the new mags. Other than that I like the Rock. I might be giving Ivan a call myself if the slide keeps locking back.

Also found that a little Floresent finger nail polish works well on the front site of the GI model.

Aren't these exactly the same magazines that Novak sells? They just stamp their name on them.

Try the Wolff extra 10% power spring. They're only $8, so much cheaper than any magazine except beat-to-death USGI mags. Never had a problem with these springs and they last forever. I've never had to change one out and, come to think of it, I did replace the springs in the three ACT mags I have for my RIA 1911A1-MS. I wasn't having any problems with the one supplied, but I pretty much swap out the stock springs for Wolff in "cheap mags" out of habit.

probably if the truth be known, wolffs makes most all magazine springs. I doubt if Smith, Ruger or any of the big companies have spring making machinery, when they can go to the experts like wolffs and save machinery costs, labor, quality control costs. Wolffs makes kahrs springs. Mecgar who is one of the biggest quality magazine makers also makes their own springs. I never considered factory magazines to have cheap springs, but when a company like wolffs offer besides factory springs, their 5 or 10% extra strength magazine springs, I like that alot. It should help work the slide lock system alot better, in my opinion..

Here's the funny thing. I bought the pistol (NEW) took it straight to the range and it shot a perfect 40 rounds . Came home cleaned it and lubed and loaded the mag. to the top left it that way for a bout ten days and went to the range and that's when the trouble started. I'll have to see how the other mags work but on the ACT mag I think I'm going the way Jocko did and replace the spring in it. The spring in my Kahr PM9 is actually more powerful than the one in my 45.

[jocko]

popeye, does wolffs make 5% more power sprngs for the kahr 45??? I guess I am to lazy to check it out..

[Popeye]

Jocko I really have no idea . Sorry. I will probably check them out for the Rock though. Thanks for the info.

[wyntrout]

They don't have anything for the .45 or the .380, yet.

Actually, in post #18, I recommended you try the Wolff 10% extra power spring. My bet is it will work great.

I haven't gone to the range yet to fire the gun (it's just been to hot to enjoy shooting)but I did pick up a Wilson combat mag for it. I also had a friend give me a couple of Pro mags that appear to be pretty much junk even though they appear almost new. The followers are very loose fitting and will not even work the slide release when there empty. The springs in them compared to the Wilson seem to be pretty much a joke.
Will the Wilson Combat springs and followers fit in them? If so where can I get them. TIA. Popeye.

[Bawanna]

I wouldn't waste your time. I'd just order up a sack full of Wilsons and call it a day. Many swear by the Chip McCormacks and many swear by the Wilsons. I'm a devout Wilson fan myself but I did get a couple 10rd McCormacks so I can be a fence sitter if needed.

[Bawanna]

If you want to tinker just for the fun of it, I believe Brownells sells the parts or you can go direct thru Wilson. I'm not certain about Midway, they might have it too.

[Popeye]

Thanks Bawanna. Just might see if new guts to the Pro mags will help at least for range time fun. For times when seriousness is a must it looks like it's going to be Wilsons loaded with FTX Hornaday Hollow points.

[Bawanna]

I guess if the Wilson parts don't help you can always keep them as spares for the Wilson mags although I doubt you'll ever need them. My last Para I don't think has ever seen a round thru it's 3 factory mags. It's been fed Wilson's since day one. Guess I should try the factory mags some day and see if they work.

I kind of keep an eye open for 1911-type magazines and parts to tinker with for the PM45, but too often the pictures are of full magazines so that I can't check out the follower and see if it looks like it might work.
There are those McCormack kits for increasing capacity(?) and function, too, but again, I don't know what they would work with. I would like to cobble a 6-round magazine together using the Kahr 5-round tube... and maybe the floorplate, 'cause I like the added grip without the too-large finger rest like some of the add-on stuff.
I could stuff 6 rounds into the Kahr magazine by just changing the follower and spring(as necessary), but it's so darn tight that I worry about reliabilility. A minimal metal follower with the matching spring, and maybe trying to find an extra millimeter of depth in the floorplate and lock might make that work.
The minimal followers are designed for the welded base-type magazines, but seem to work okay with the matching spring... otherwise, the follower might pop out or not work correctly.
Oh, BTW, Boomer got a new frame and is essentially all new. I hope to get it back from Kahr soon... if my FFL dealer gets around to sending them his FFL... new serial number & registration.
I'll have to break it in again... they fired 70 rounds with the new frame without problems. They tried other frames and duplicated the mag-failure problem until the new frame was tried.
You might check out the spring kits that Wolff makes for a lot of guns. I bought the kit for my S&W 645 and got every spring in the gun, including one for the magazine. I'm sure I can use the recoil spring, but the several dozen other... some tiny as heck... I have no clue, but they may come in handy for any gun in the future... spare parts... $20 something for the kit.
