I recently got hold of a P380 barrel locally for very cheap and wanted to try it out in the CW380 I have. Before I bought, I saw some have done this successfully, and one person noted it was a tighter fit in the gun as i recall. Well, I tried it out today, and in placing the barrel in the slide, I did notice the barrel was a tighter fit. It was perfect with no slop when fully situated in the slide. The CW380 barrel had a very slight front to back movement, almost imperceptible, but definitely there. Now every gun is a tiny bit different due to tolerances, etc., so maybe others have a barrel that fits exactly as well as this P380 did, dunno.

The other thing I noticed was that the feed ramp seemed just ever so much wider than the CW380 barrel. I tried some calipers, and it seemed to suggest they were very close in width, so maybe it was an optical illusion, not sure.

So what I was hoping, being the obsessive gun owner that I've become, was that maybe my gun might cycle the Xtreme Defender bullets as it does for some other folks with these guns, a number of them being P380 owners. I always wondered why one would cycle it and another wouldn't. In the past, my CW380 routinely had a misfeed jam on the ramp as the bullet veered off to the right where support is lacking in the Kahr feed ramp design. So would the new barrel make a difference?

Well, using the technique I described before, alternating Xtreme Defender ammo with cheap Freedom Munitions ammo in the mag, I set off to my home range to find out. Short answer is, the Xtreme Defender cycled each time perfectly well. By ejecting the unfired Xtreme Defender rounds each time they were chambered, I was able to redo the test several times without wasting the preciously expensive XD rounds. It cycled from top to bottom in the magazine. I didn't do enough to verify it will always be reliable, but it certainly was a different finding than my previous attempt with the stock CW-380.

I like the Lehigh XD rounds as they make a 380 about as effective as a 9mm hollow point, which makes the gun a very handy concealed weapon. The CW 380 was very accurate today with dings on the steels almost touching one another in many cases, at 20-30 feet.

Will need to follow up with more testing, but I'm feeling better about the gun, and may carry it more this winter than I had planned (originally was only going to use a G26 or a Para P10.45, both of which are stupendous carry options, but even so are 2-3 times the weight and size of the CW380).

Does this mean you should go out and buy a P380 barrel? I don't think so. I only took the chance because I got the barrel for basically $30 plus shipping, about the cost of a box of XD ammo. Take this as simply one more data point in the CW380 story.

Great info that could make a big difference to folks looking to maximize the effectiveness of such an easy to carry weapon.

With the weather getting cooler around here, it's getting easier to conceal my larger carry choices. I'm considering carrying my CW380 in lieu of an extra mag though. Since I carry my spare mag for my MK9 in a leather mag pouch in my weakside pocket, I'm as fast or faster with a BUG in a pocket holster. The effectiveness of the XD rounds certainly makes this a viable option.

Even though I'm just about 15 minutes away from Lehigh Defense (no shipping), I chose the Underwood +P version of the XD rounds. Nickle plated Starline brass, CCI primers, and a choice of standard velocity or the smokin' hot 1400 fps +P loads works for me. Price works out pretty close, and Underwood has specials pretty often for free shipping. The slick nickle cases may make a difference in feeding more consistently too.

The icing on the cake is the fact I shoot my CW380 ridiculously well. With all the great pistols I own, it's easily one of my favorites. I should probably get another one, just in case...

Ed, I'm 45 minutes from Lehigh, so close as well (Bucks). I have the exact same feeling about nickel plating. Not only is it slicker, it lasts without corrosion, which can really roughen up the brass. Lehigh should switch over to nickel as well. I also go for the +P, especially for the controlled fracture type, to help with penetration for that particular bullet. So I get Underwood stuff as well. There is a third outfit doing Lehigh that is somewhat cheaper, but I forget the name off the top of my head. Underwood is top drawer though.

As happens often, I too have been wondering about the reliability of the P380 compared to the CW380. Is there a difference and if so why?

Nice write up.

None that I'm aware of. I guess the same question could be asked of a PM9/CM9 comparison as well.

Yes, my thoughts too.

Hickok45's review of the CM9 was favorable compared to his beloved PM9. In fact he was suggesting that today he'd likely choose the CW version.

Maybe there is, maybe there's not. We can't really know unless someone owns both, shoots both with the same ammo side by side, and then tries other various ammo as well in the same way ... and then get at least 19+ other folks to do the same. Highly unlikely to get that info, so we are left with anecdotal evidence. The fit was different for the barrel, if ever so slightly, and of course, they are different barrels, for sure, one being normal rifling and the other being polygonal. Are they different apart from that? Not sure, but I did have a different experience with the problematic XD rounds, which is of prime importance to me.

i just ran the Underwood 65 gr extreme defender through my cw380, love the huge X's put into the paper, and where rather accurate.

after viewing the the ammo on several youtube gel tests using the same length barrel, then comparing the results, this is going to be my carry ammo.

for recoil / followup shots chose the "regular" and not +P, and also to retain the 12-18" penetration. i found it to be very manageable in rapid fire. i believe it to be and excellent combination of tissue damage and penetration, especially for a short barreled .380 - seems to "up" the caliber.

also looked into the controlled fragmenting type bullets, maybe will buy and try for functioning then alternate rounds in the magazine.

i went with the Underwood as they also claim to use a lower flash powder, though i haven't compared it to anything else in dim light as of yet.

I was using extreme penetrator in .380. The underwood would not feed in my CW 380 but the lehigh fed perfectly. I figured the brass made a difference
