CW45/P45: Flush fit magazine - UPDATED

[Deano]

This is a follow up post related to this mod. I made three mags for my CW45 using the mecgar mags. Initially they fed and fired fine, but would not lock back the slide after the last round. After starting to have the same issue with my kahr mags, I went and got a size 6 torx screwdriver and tightened the slide lock lever spring. Now they all lock back the slide after the last round. Thought this might be helpful info for someone with the same issue.

The Winchester whitebox 230gr FMJs with their flat point have had problems with the steep feed ramp on the Kahr. I'm guessing round nose FMJs work better and hollow points with a smaller opening as well.

Not wanting to piece meal and build a flush fit mag has anyone had any luck with the 7rd Wilson officers model mags with some modification?

I have a 1911 Service Mag Plus, .45 ACP, Compact, 6 Round, Stainless coming tomorrow. I will let everyone know how well it works.

Well, back to the drawing board. I converted two Metalform mags to use in my CW45. They hand cycled fine, but when I got to the range they wouldn't feed. Maybe I need to take just a little more off of the exttractor side of the mag, but I'm worried about getting into the feed lips. On the other hand, I took a nondescript government Model mag that I had, and it worked fine with no mods at all. Go figure.

Forgot to ask, what defensive ammo are you running in your CW45s? I tried Hornady TAP, and it wouldn't feed. It could get pretty expensive trying different loads, but I'm thinking something with a more rounded ogive. Any thoughts?

I use Speer Gold Dot or Federal Hydra-Shok 230gr. loads.

Thanks. The TAP loads I tried hung up on the nose cavity. Those two should work well.

I have had problems with all of Hornady's 45ACP ammo in my Kahr.

I have had good experiance with COR-BON PowRBall ammo as well as Remington Golden Saber. I still have some COR-BON DPX and JHP ammo to test out as well as some Aguila and Fiocchi.

Thanks, guys.

can you buy just the followers and springs?


Found this, is this the right follower for the cw45's?

Yes, you can. Here's a link to a follower and spring kit:

That is the follower would work in a CW45magazine.

Always look for a "KIT". You get more for your money! This is a good way to save money on springs and followers and base plate parts... base plate and locking plate.

I wouldn't advise the "spring kits" though, as that might tempt you to make unneeded changes... fixing what isn't broken!

First post and some great info to be found here.

I used a CMC match grade compact 7 rd mag. part #14120. Mag fit perfect with the base plate lip touching the bottom of the grips.

Trimmed the top as stated in all other posts. Hand racked all 7 rounds none of which needed to be "sling shot" in fact you could ease the slide closed and all rounds would chamber no prob's . But....the last round will not eject with out dropping the mag. All rounds other than the last one will eject effortlessly whether racking quickly or slowly. It looks as if it would eject if the casing was spent. The slug portion of the round is what is hitting the top edge of the chamber mouth and stopping the slide.

After reading through the posts I saw where most are saying to stay away from the metal non-skirted followers. Thinking this follower might also be my problem I inserted the stock Kahr follower and tried both the Kahr and the CMC spring. Giving me a 6 round cap but still leaving me with the issue of the last un-spent round not clearing the top edge of the chamber mouth.

I could not find in anything addressing this issue in the previous posts.

Has anyone experienced this problem.

Tested my set up today. Ran 50 rounds of Fed. 230 gr fmj target ammo and 10 rounds of WWB 230 gr fmj using the 7 round CMC mag with a Kahr follower and the CMC spring.

As I had hoped, the issue of the last unspent round not ejecting, while bench testing, without dropping the mag was a non issue during range time. I only experienced 2 failure to lock open which were due to me experimenting and placing my support hand thumb on the slide lock lever pivot point. After correcting that...no more FTLO. I did have 1 FTFeed with the round nose diving and holding the slide open. A quick tug and release on the slide cleared and chambered the round.

Shot 20 rounds using the 7 round Kahr mag and had one Failure to go into full battery. Smack on the back of slide and problem cleared.

I have noticed that this pistol likes to be kept clean. During break in, after 200 rounds of fmj, I started trying different jhp loads and she started to give me all kinds of issues. Enough to start worrying me. Gave her a good cleaning and the next trip no probs.

Thanks for all the info for the flush mag trick.

Does your slide retract about 1/2" before it hangs up? If so, you may have a problem similar to mine. It's not the last round, but any round that has to extract over a SWC profile bullet next up in the mag. The extractor seems to let the empty slip down just far enough to hang up on the next cartridge in line, and if it has a sharp angle to get over, it just won't do it.

I had the pistol apart yesterday, and I can't see any way to tighten the extractor, with my limited skills, so I just use different ammo.

Try ejecting an empty case, and if it still hangs up that may be your problem. Something in the follower, case feed angle, etc.

Good luck!
