I talking personal defense. Just how good is this round. The 45 is not fast to begin with. Can it be effective in a three inch barrel?

it does fine, i just prefer a 4" barrel minimum for reliabilty IMO.

I'm thinking of the new Kahr with a 3.4" barrel. Will any loads perform well with a short barrel?

When talking short barrels (less than 4") and 45 acp, in my opinion reliable expansion is not there with just about any weight or bullet type---BUT remember that the worst it can get is like using .45 ball if it doesn't expand. I can live with that.
I have a Springfield micro (3 1/4"), and I carry it with 230 gr. JHP--tried several 185's and even the Fed. pesonal defense 165's, but point of aim/point of impact was greatly affected. The 230's all shoot dead nuts. Being I don't have faith in the lighter rounds expanding any better in these ULTRA short tubes than the heavy's, I would rather have a 230 gr. JHP act like ball than a 185 gr. JHP act like ball.

I recently witnessed the new Cor-Bon 160gr DPX "Compact gun load" run through 10% Ordnance Gelatin using 4 layers of Denim as a barrier, from a Glock G-30, and a 5" 1911A1.

The stuff expands completely, just like the heavier std .45acp load, and still penetrates 12" from the shorter barrel.

It hit POA/POI from the G-30, and is a standard pressure load.

I shot load in a G-30 for accuracy and reliability, and found that it felt like plain old Harball, shot as accurate as I can hold the sidearm, and didn't have any failures to cycle in the 30 rounds I fired.

It's a slight bit more expensive than some other loads, but I noticed the velocitys and penetration depth were very consistent.

It might be worth looking into if the stuff feeds reliably for you.

Hope this helps!

Speer is marketing JHPs designed for short barrels. I have purchased some bullets for a S&W model 442. About to reload some. The designation includes a "SB" and I beleive they have some for .45ACP. Not sure which ammo manufacturers might use them at this point. Speer could probably give you that information.

I think that the hot Cor-Bon loads(Cor-Bon ammo is meant for defensive and hunting use in handguns), with the thin walled hollow points they use would give you excellent expansion out of a short barrel auto.

The Cor-Bon DPX is a departure from the past

No jacket, no lead core.


Fewer variables.

Old rules and accepted standards are out the window.

There is sure to be some politics afoot, but this load meests SAAMI specs, opens up from short barrels, and meets the FBI Criteria for penetration.

The std. loads from everyone else just ain't getting it in the short barrels.

The politics of this, aside of course.

I have to agree with S-28 that the Cor-bon DPX and the Magtech First Defense, that load the Barnes hex all copper bullet, are the way to go with a short barreled .45. I have a Kimber Ultra Carry and I carry the now defunct Taurus Hex in it right now. I have heard from some pretty reliable sources that the copper bullets are the only ones that reliably expand and have sufficient penetration from a 3 inch barrel. Check out That is my primary souce for the info. They are under construction again but I think you can still cruise and search the discussion forum. Hope this helps.

I would like to answer this question. I have 2 3" compact 45's This is what I have found in my backyard testing. Useing 230 ball Win White box I shot a 1/4" peice of Lexan{plastic} at approx 10' round failed to penertrate. It just made a large bubble on back side. I shot some season 1" barn wood and rounds failed to even go in depth of bullet. I removed with my fingers. Tried same test with my Govt. Nice hole in Lexan and same with the wood. My Compacts are now loaded with a lighter round 185 silvertips and the CorBon DPX is on the way. I love the small 45's but they need a lighter bullet . I don't belive their a good idea with 230 even +P Camp using a Defender got 1080 fps in his test of CorBon Thats fast enough for expanstion and Penteration at SD range.

According to testing done by Ammolab, the ranger 230 loads do very well from short barreled pisols.

How about 2 layers of 16ga steel, 2" apart, before going 5" into 10% Ordnance gelatin?

The new 160gr DPX just flat works in the smaller .45's.

The older 185gr load penetrates more, but then I don't rely upon a micro .45 daily.

Have yet to have a malfunction or burble with DPX.

Mind the over thinking!

Thanks for bringing the Cor-Bon load to my attention, and the good information. I will be trying the load in G30 when I can get my hands on some.

I use 230gr hydroshoks & goldensabers in my Glock 36, they both expand and have the depth you want
