Looking at Marvel conversion
[size=81] I have been looking at picking up a Marvel type 1 conversion for my RO with an UD2 mounted on it. I was wondering how the aluminum lock back versions hold up over time.[/size]

Re: Looking at Marvel conversion
I've had better luck with the Nelson conversion. I replace several firing pins and two slides on my Marvel during the time I owned it. To be fair, I shot it a lot over about six years. I've had a couple Nelsons that I've given to my sons on lowers that I put together for them. They've run very well with no breakdowns. I'm currently waiting for my third one. I ordered a combo unit this time. All my sons are properly equipped so I should get to keep this one.

Re: Looking at Marvel conversion
I like the Marvel non-lock back version. I think it was a bad idea how they added a larger chunk of material on the slide to aid in wear for locking back. Most of them get chewed up from the slide stop because it doesn’t fully engage the slide lock catch. Also when you use thumb to release the slide it will hit your thumb. Poorly designed in my opinion. I have a non-lockback and a steel slide lockback that I don’t lockback I prefer a old used Marvel over all the available conversions out there. They have the best barrels and will really shoot well.

Lockback is over rated once you get used to not having it. Some of the high end Euroguns (Pardini, etc.) don't have it at all.

I love my older non lockback. Took some time to get it right for the ammo it likes, but is now 100%

I have an older non lock back. Dang fine shooting piece of equipment. I can’t say much for current production.

I have the steel lock back edition & it runs like a Swiss watch on CCI std velocity ammo.

I've got a new steel lock back and it works great
I've got a new steel lock back and it works great. I got it last year, It took about 800 rounds to break in but it is very reliable and accurate with CCI SV.
I'm at about 4K rounds in 10 months. The slide stop had to be replaced because it burred up on the edge but the new owner (Travis) told me it was a due to the steel the prior owner choose for the part. He replaced at no charge it with a new unit he made from harder steel and it works great.

Lol so what is the excuse for the burring up on the Aluminum version. You could have gutted a fish with mine. I've peeled away all the sharp bits and Jon has it tuned to not lock back. The Nelson method with the embedded steel pin works much better.

How old are you talking about and how do you identify the age. I have one I haven't been using.....maybe I should be.Jon Eulette wrote: I prefer a old used Marvel over all the available conversions out there. They have the best barrels and will really shoot well.

I can't speak to the lock back versions but have an non-lock back Marvel Al slide on a dedicated NM frame. Shot a Ruger Mk3 before this and it was a great improvement for me as I prefer 1911 straight back trigger pull. But to make it run well with CCI SV I needed to install a reduced power hammer spring and 8# recoil spring (comes with 9#) so be prepared to make some tweaks there. Runs near 100% reliable now so long as it is fouled after cleaning. Most on forum seem to favor Nelson and that's fine but been happy with Marvel and their customer service.

Re: Looking at Marvel conversion
I’m not the best one to Date the Marvel changes over the years. This is probably a good STICKY to make for identifying the years/changes; barrel blank manufacturer, extractor width, etc. I don’t know if serial numbers play a role as well. I just know from experience the early conversions shoot better than current/recent conversions. I know you could pay extra for a better grouping barrel, but I believe the early pistols all shot excellent due to Shilen barrel blanks. I have personally Ransom tested several 0.5-0.6 barrels with many different ammunitions. Mid 2000’s (05-06) were good years.TomH_pa wrote:How old are you talking about and how do you identify the age.

Ok, thanks
I guess the best thing to do is have a Ransom rest shoot off ,see which one wins

Re: Looking at Marvel conversion
Thank you all for the replies. It looks like I'll be going with the non lock back. I only saw a couple of comments on the aluminum model though. Has anybody noticed any negatives with using the aluminum version?

I also have a new (this year) steel lockback. It is unreliable with Norma Match (too soft) but runs fine with Federal 711B, old Western SuperMatch MkIV, CCI SV. Pretty doggone accurate. Keeps up with my HS Victor. Running it in a George Madore SA 1911 frame with EGW 19# mainspring, EGW lightened hammer and the as-rec'd 6# recoil spring. I use the Marvel plastic mags and GSG metal with a standard mag release.
