I understand that Oly is the only mfg doing a .40 upper currently, but I am wondering just how hard would it be to make a Colt-pattern .40?  For the most part, the 9mm mags work at reduced capacity with .40 in them, so why couldn't you use a bolt with a .40 headstamp and just machine out the channel for the Colt ejector?  If necessary, couldn't you make the ejectors shorter to match the .5mm offset in case diameter?  Just a thought...

Get their new Glock magazine series rifle and you can get a 29 round .40S&W GLock magazine and be good to go.

handled that one at SHOT, didn't like it very much.  i'm not much for oly in general based on their extractor ejector, much prefer colt pattern.  glock mag model doesn't solve extractor ejector problems.

I posted this in another topic here recently, You should be able get away with using a COLT/RRA/ASA/Garison bolt, have the pocket opened slightly to accept the 40 case head, simply cut a barrel from blank, chamber it, and run with it....

In your experience what is the problem...

I have run 10 of thousands of rounds through 9mm & .40S&W full-auto without the ejectors ever breaking.  In the past Oly ejectors were made of a softer metal and would break.  New ones have been fantastic.

I don't have any personal experience with Oly pistol caliber uppers, only their CAR hardware.  I haven't talked to anyone (in person) who has owned and shot an Oly pistol caliber upper and hasn't sold it after a number of ejector breakages.  I had never doubted this because my CAR15 came with Oly hardware and all of it is badly out-of-spec and poorly finished.  It may be different now, but it doesn't change my overall opinion of their product enough to justify dropping hundreds of dollars on a design that I see as flawed when there is another product with a proven design and a better reputation for the same money.

Oly's system has sold thousands of units and many shoot full-auto...

Had you said, when I had an Oly 9m it did so & so, your story would carry some cresidence.  To say it sucks because I think it is bad, seems very unfair - to any manufacturer.

It works and works well, in my personal experience.  I have shot all of the pisto calibers and it works well.  I have sen the Oly system used in machine gun competition many times without any failures.

I think we would all agree tha the Colt style and Oly style are not the PERFECT system, but both work very well.

The Oly .45 upper I had runs flawlessly.   Never broke anything.   That said, you could go with a Cav lower / buffer and hahn block for greasegun mags and stuff about 35-37 .40s in it, cheap mags too.   Just an alternate thought.

If you'll notice, I had underlined the key words for emphasis.  The point I was trying to make is that the only experience I have with their product is negative and I wouldn't pay hundreds of dollars for anything made by them unless I had no choice.  I'm not saying all their stuff is crap, because I don't know if it is, just that I'm not taking a chance with their products when what I do own from them is crap.

Maybe I read too much into your statement but it has double negatives along with a negeative experience "after a number of ejector breakages."

Well, first of all, there is no double negative as "have not talked to anyone" in no way modifies "(said person) who has not sold it after a number of ejector breakages."  A double negative would be "have not talked to no one" or "didn't not sell it after a number of breakages."  The negative experience is not my own and in no way did I ever claim it to be, so I'm not sure what it is that you are trying to say.  I thought I made myself clear enough, at least with the later post, for the average person to understand that my personal problem with Oly products is my personal experience with their crappy products (which I acknowedge may be a thing of the past) and that the opinions of others whom I personally know only lend support to my opinion.  I did not post here to make an Oly-bashing thread, nor do I intend to make it one now, so unless you have some need to pre-emptively defend those who are not being attacked or have a personal problem with my grammar, I think we are done.

I've got everything to complete my CavArms lower setup for a .45 but the upper. However, I don't own a .45 pistol. Got several .40S&Ws though. Would like to simplify my ammo situation and stay with .40.

Can you use a CavArms lower, Hahn mag well block, and M3 Grease Gun mags with an Oly .40 S&W upper? Has this been done before and what are the traps for the unwary??

You would have to play with feed ramp, more than likely.  Personally I would not do it unless it was for the fun of it (i.e. no trust my life on it).

Actually using the Hahn block there is no feedramp.  If you can get it to feed from the mag which should be simply experimenting with the feed lips I dont see why it wouldnt work.   I toyed with the idea but lacked a .40 upper to really check it out.   I did get .40s to feed into my .45 upper when hand cycled.  I was just satisfying personal curiousity with that, I'm not 100% sure the .40 upper will work but maybe you can borrow one to check it out for sure?  

My 2 piece blocks did have a forward feedramp unlike the Hahn setup.   They eliminate the need for the feedramp by moving the mag further forward in the magwell.

I hope you do not read something into everything someone says!  

My point was/is that complaining about a different product than being talked abuot, that one has not used, does not help, IMHO.

Had you said, I have used the .40S&W Oly rifle and then state your complaint, that would have been useful.

Your incorrect statement,


...but it doesn't change my overall opinion of their product enough to justify dropping hundreds of dollars on a design that I see as flawed when there is another product with a proven design...


No one else makes a .40S&W so how can there be another proven design...

You can have the last word.

I'm not trying to read into everything someone says, I am just responding to posts that I think got way off point here.  My original post was:

For the most part, the 9mm mags work at reduced capacity with .40 in them, so why couldn't you use a bolt with a .40 headstamp and just machine out the channel for the Colt ejector? If necessary, couldn't you make the ejectors shorter to match the .5mm offset in case diameter? Just a thought...


I was not asking for someone to tell me that the Oly pattern works fine, or to argue about the merits and deficiencies of the Oly design.  I don't care for the Oly design based on its design (and I said I didn't want to make this an Oly-bashing thread so I won't elaborate).  My above statement is not incorrect, as I am comparing designs and not specific calibers.  It does not matter that no one makes a .40cal Colt, as that is exactly what I am asking about fabricating.  That said, you are entitled to your opinion as much as I am to mine, and this thread was not intended to be about Oly in the first place.  how

40 S&W can be used in the M3 mags.... currently common practice with Uzi using the lower with a M3 magwell so as to get 30 round of 45acp when running the 45 kit in Uzi.  You simply close the lips slightly to retain the 40 case, and the mag will hold up to 40 rounds with follower mod,  or 35-36 rounds as-is.

You can feed 45acp from the mag also, I do it withmy Uzi, nothing like dual purpose mags.
