anybody have one? whats your thoughts on it for hunting. i have a old 45 frame i was thinking about turning it a 460 rowland looking for input before i spend the money.

I have had a conversion and they are okay.In my opinion they are pumped up a little more with hype than reality.It should be more than enough out to say 25yards but your old 45 frame better be a good one.

why is that cotton? does it beat the frame up good?

They won't do them on certain brands, Llama, AO, RIA are a few:

We do not recommend this kit for installation in
IAI (Israeli Arms International) - We've found the top lugs in the slides of the Philipines produced 1911s to be soft! We've not tested the Israeli made guns but would recommend extreme caution.
Rock Island Armory
Auto Ordnance
Llama
AMT
Charles Daly
Essex
Remington Rand
Any "GI" 1911 (note: Springfield Armory Current Production models excluded)

Some of the slides, springs, etc. are not strong enough in some of the brands to handle the 460 Rowland. As far as hunting the round is stronger than a 357 Max., it is often compared to the 44, but it is more similar in power to the 41 Mag.

It's a nifty idea but if it's not all it's cracked up to be. Wouldn't a 10mm be easier?

I would imagine a guy would want to put a good buffer and a stout spring in it to keep from mushrooming the frame. I run both in my Taurus and because I shoot a healthy diet of +P's in it.

the frame is full with wilson combat springs and full lenght giude rod and recoil buffers.
