This has probably been addressed here before but I cannot find it.

Is anyone using this system in 10mm or 460 Rowland 1911's?

How do you like it and what spring weight are you using?

I don't have one.  Closest I could find in search was this:

http://10mm-firearms.com/gearequipment/any-one-use-an-efk-rsa-for-a-glock-20/msg72801/#msg72801

I would have sworn there was a thread about them though.

Thanks for the response anyway.  I have trouble with the search function here at times and I thought someone has to be more savvy than I might help.

A guy over at Colt says he has had good results in his Delta with a 22 # spring.  Firedragon's website brought up the 460 Rowland.

Thanks again, maybe someone else has some experience.

Added later:  The Colt Forum is a Collector's Forum so I wonder sometimes about the data posted.

Looks very similar to the Sprinco system for $35 less.

Do you have a link for the system you are talking about? I have a G21 long slide with a 460 Rowland barrel in it. I have the heaviest spring that Wolff has in it but it is still hammering pretty good. I DO NOT have nor do I want a compensator on it so I'm exploring alternate solutions. I do shoot it suppressed when hunting so I'm sure that isn't helping much either.

I know nothing about the company but I would call on the 460 setup you have.  I shoot a 460 set up on a 1911 with a comp.

Here is a company with a similar product that does address the 460 Rowland.

No go for anything from EFK or Sprinco.
