Yagi Posted October 20, 2020 Share Posted October 20, 2020 Planning on another Single Stack Build. Are "NO STIRRUP" legal in this division? or should I go with the conventional design with a STIRRUP on the slide. Thank you, Link to comment Share on other sites More sharing options...
jwhittin Posted October 20, 2020 Share Posted October 20, 2020 (edited) I don't know what a Stirrup is? I couldn't fine a good explanation/example. Some people referred to it as the "ball cut". Is it the same thing? But as far as slide cuts go it boils down to if it is deemed to provide a competitive advantage or not. Milling D4-21 and 22 Permitted - Duplicating features that are on a factory, mass produced slide available to the general public is permitted. Permitted - Milling of the slide to insert sights, add or remove serrations, such as cocking or flat topping, tri-topping the slide, lowering ejection ports, cuts that are minor and cosmetic in nature are permitted. Prohibited - Slide lightening, cuts, ports, or any milling deemed to provide a competitive advantage. Edited October 20, 2020 by jwhittin Link to comment Share on other sites More sharing options...

The question is if I can do no stirrups and leave it alone say on a unique slide as oppose to classic slide cut. Link to comment Share on other sites More sharing options...
ChuckS Posted October 20, 2020 Share Posted October 20, 2020 D5 23 Permitted features (second bullet) • Duplicating features that are on a factory, massed produced slide available to the general public. I think this makes it legal. Since you are leaving material on the slide, the gun is going to be heavier. Could be an issue with a 9mm. Link to comment Share on other sites More sharing options...
jwhittin Posted October 20, 2020 Share Posted October 20, 2020 Ah, I understand now. I don't recall seeing any mass produced 1911 that doesn't have some form of ball cut. Are they available as a standard option? Link to comment Share on other sites More sharing options...

WFargo Posted October 21, 2020 Share Posted October 21, 2020 But that one seems to have a full length dust cover.... Is that allowed in USPSA? It's not in IPSC.... (but we're not talking IPSC of course...) Link to comment Share on other sites More sharing options...

IPSCLUVERRR Posted November 3, 2020 Share Posted November 3, 2020 I went to nationals this year with a full profile slide with no ball cuts. Did not make weight in 9mm but does in .40. No issues with passing gear check Link to comment Share on other sites More sharing options...
Bakerjd Posted December 11, 2020 Share Posted December 11, 2020 You can get away with a LOT of milling or no milling in SS. Belive me. I build a DW PM45 that has full length steel guide rod, steel smith and Alexander magwell/MSH and a not tri topped slide. It is just under weight with mag. I also have serrations on the side of the frame where your thumb goes. That we actually talked to troy about and is good to go. Link to comment Share on other sites More sharing options...

Not part of the OP, but "Factory installed light rail attachments if the dust cover is no longer than 3.25 inches measured from the rear of the slide stop pin to the front of the dust cover."

JayWord Posted December 18, 2020 Share Posted December 18, 2020 Rich Dettelhouser from Canyon Creek did what he called a Krebs cut on one of my 9MM Single Stack guns. I talked to Troy and he said it was okay because it did not take any more material than tri-topping the slide. It also did not make a hole/port which is specifically prohibited by the rules.

shred Posted December 21, 2020 Share Posted December 21, 2020 Probably, but why?. If you really wanted a fast cycling gun, put a commander slide on it. Go short enough and you can even have a bull barrel. Link to comment Share on other sites More sharing options...

Take a look at the Dan Wesson pic I posted. 100% SS Legal. The milled out areas of the slide are .50 thousands deep. I'd recomend not going that deep unless you are ok with the possibilty of cutting though the slide. We normally cut them at .20 or .30 deep.

DirkD Posted December 23, 2020 Share Posted December 23, 2020 A 2011 is a legal single stack?? The Smith is not legal??? Link to comment Share on other sites More sharing options...

Their other models are double stacks. It depends on the size of the magazines the gun accepts. Wide body frames are not SS legal. See D5 Special notes. And because of the ports in the slide of the S&W it is not SS legal. See D5-22. Edited December 23, 2020 by jwhittin Link to comment Share on other sites More sharing options...

No. You also cant use SS mags made to fit a double stack frame. There is language about that in the rules. Don't know where off the top of my head.

jwhittin Posted December 23, 2020 Share Posted December 23, 2020 The outside grip width is 1" (consistent with single stacks). So I think it was designed for a single stack mag. Its not a double stack grip modified to accept a single stack mag. Link to comment Share on other sites More sharing options...
