Perfect timing. As I work on my 1911 builds I have been contemplating adding the marvel ramp. As I study the opinions of men smarter than me, most have made up their minds that it has many negatives. Although I’m not a Bullseye shooter, performance and accuracy of every round is important. To say it only improves the first round, not the rest means that for 12% of the rounds it’s not important (1/8=12%.) My hesitation was caused by comments of weakening the breach face. I have the slide of a 10mm I have been working on on my mill and I think I’ll give it a try. It will only take 15 minutes or so and most of that is setup. Thanks for the timely education.

It just makes sense mechanically

[@sk21rt54]

And i love seeing you work. The gun you worked on for me is my favorite carry piece.

[@Mohel_Tactical]

Love it! Add it to all my 1911’s

You know, I never knew about the "marvel cut" when I got into 1911s. I got a Tisas Stingray just to check out the platform. Ended up really enjoying it, so I ordered a Stealth Arms Platypus because I wanted a doublestack, the mags are cheap (glock) and I could customize it. It is smooth, no hang ups, just beautiful (imo). I got a prodigy recently and even though it is smooth as well (after some racking and cleaning off of cerakote), but I can feel the disconnector when riding the slide forward. Took them apart and that's when I noticed the ramp cut into the Platypus. I looked it up and learned about the Marvel cut. I was floored they added that into the design, and wondered why everyone didn't do it. A cheap Turkish 1911 sure I can see not doing it, but....what's everyone else's excuse? LOL

1911s have a purist following that thinks anything you do to modify one is almost sacrilegious. I have over 30 of them in various lengths and calibers. Probably half of mine have been modified in one way or another. We have an advantage that John Browning did not have, and that is a hundred years of data to look at. I have ramped a few of mine and it does make for a smoother operation.

[@RobSchauland1911]

It does indeed lessen the "cold shot" effect.

[@Tlklmk]

I NEED those grips!!!!

[@TheWorldRealist]

It makes sense mechanically

[@sk21rt54]

I checked a pile of different 1911s at my local lgs yesterday. Out of all the different models, a bull armory had the smoothest feeling slide when I racked it. In your opinion, what makes the slide feel so smooth on some models?

[@mastergunworks]

There are a number of things at play that can affect the smoothness of a 1911 cycle. For instance, polished surfaces, spring weights and quality, slide to frame fit, disco slot and barrel fit all play a role. The amount of hand fitting and tuning usually play a big role.

[@BrentJoyce-ko7vj]

I decided to do my own modification of a ramp with a Dremel tool. Do you believe some improvements can be made without precision tooling?

[@cslate36]

I did this big improvement

[@davidsawyer6784]

Do you include this “upgrade” on all the pistols you build or just as ordered by the customer?

[@mastergunworks]

On my full builds this is standard. It is optional upgrade to the gunsmith packages but is pretty reasonably priced.

[@lightspeed2121]

Believe me it’s bob marvels deal,

[@XuroX.]

Smoothness and less wear yes, but I'm failing to understand how that can affect accuracy....

[@davidsawyer6784]

I’m am preparing to do this cut on my milling machine but I can’t find specific measurements (Depth, width, and length) and I don’t have, or haven’t seen a slide with this cut done. Can you help a fellow smith with some numbers. I could guesstimate but would rather have an experienced smith toss me a bone. Thanks in advance. I await with great interest.

[@mastergunworks]

Go to my email on my website and I will give you some specifics. www.mastergun1911.com

[@TheWorldRealist]

Rather than a ramp cut, beveling off the center edge would create probably 80% of the mechanical benefit without removing as much material. Not a gunsmith but trained as a toolmaker in the dark ages!

[@robertscibana2236]

Does adding the marvel adaption put excessive stress on the slide at the end of its rearward travel? Do you feel the need to add a recoil buffer after making the modification? Thanks in advance…

[@mastergunworks]

No, it does not. There is so little material removed the stress on the slide is virtually unchanged. In fact, I don't normally recommend using recoil buffers at all unless you are shooting heavy loads and just target shooting.

[@robertscibana2236]

Ty!

[@EasternSunset007]

4:00 how does this improve accuracy?

[@ArmeroPR]

It doesn’t

[@jesselopez1922]

Didn't you void the warranty by doing that?

[@mastergunworks]

Any custom work done by anyone, but the manufacturer will most likely void the warrantee.

[@richardkluesek4301]

Time and money to do these wonderful adaptations. The 1911 was meant to be a mass produced conscript issued sidearm not the custom trophies we have made of some of them.

[@TheRealZJE313]

Does this void my Life time warranty?

[@mastergunworks]

Maybe depending on the manufacturer

[@innerverse1809]

Obvious issue, you were able to fire the pistol, and the slide was NOT in battery. This may be an issue with your firearm and not the modification. Or you machined both ends which seems improper.

[@jesselopez1922]

Why the whispering?

[@mastergunworks]

Its a secret.

[@skam268]

you guys talk too much as you are some technological geek, dont waste my time
