Shorter slide on an open minor gun (with no comp)?

I'm toying with putting together an open minor 2011 because, hilariously, it would work in IDPA Carry Optics provided I don't use a comp. The build plan right now is a 9mm with a dot mounted on the slide. I know lots of folks are using mid-length slides on their major builds to reduce reciprocating mass but they're typically pairing it with a comp - would  the same logic hold true with no comp? Or should I just stick with a 5" slide?

Guncrafter makes one. STI has the DVC carry. I've seen several at 3 gun (normal to run a 9mm minor in 3 gun). Lots of commander length 9mms put there. I see no reason it wouldn't work. And with a dot, sight radius isnt an issue anymore.

 

You're not treading new ground I dont think.

Didn't think I was. I was mostly curious if anyone here had done it and what their impressions were.

3 gun guys seem to like it.  fewer long pistol shots on most 3-gun stages so the decreased sight radius isn't a problem.  plenty of barrel to get enough velocity.  lower reciprocating mass keeps muzzle jump in check.  I'm doing a 5" build for 3 gun right now, but I'm sticking with open sights.  I had very seriously considered a commander slide with a sight block, but figured I'd save that build for another day.  Everyone who has one I talked to seemed to like it.  (and I think the DVC carry is the nicest looking pistol STI makes, so... there's that...)

There are many ways to reduce reciprocating mass.  Tri-top the slide.  Cut an Open gun scallop on the rear of the slide and mount the dot on it.  Use a bushing barrel.  I'd stick with a 5" slide because there are more tuning options.

Hello: I have a IDPA bull barrel 2011 I built a couple of years ago. It has a cut down 5" barrel and slide to meet the rules. It also has a custom guide rod and uses a flat recoil spring. I run iron sights on it but it is a very fast pistol and accurate as well. Thanks, Eric
