oh man that's stupid simple.  how can they not know this!

[LeMat]

Probably because most folks wouldn't notice it and get in touch with 'em.  Or maybe they do and just don't think it's important enough to retool.

Good on ya and your sharp eyes!

Patent infringement perhaps? A hard cut for some CNC equipment? The non OEM way is a cheaper production procedure? Interesting questions to me, but I doubt I'll ever learn the answers.

I think I'll take mine over to my barrel maker on Wed and have him look them over. He loves obscure questions and problems. Hes run his own tool and die shop for over 20 years and has built semi auto rifles from scratch so he should be able to offer a valid opinion and explain to me what the h**l is going on with these barrels.

guide rod only sticks out further IF the slide is put on the frame. Otherwise it lines up correctly.

I agree, but good luck getting them to believe you or understand what is going...well now that it's posted on a forum they might take notice.  But I made a video for them and wrote it all out before and they (David-owner and April) just didn't comprehend it.

Their response to me was completely unprofessional. Like I said it was frustrating and sad. Aren't the cuts on the SLB barrel beautiful??!!?  Anyway, I will not buy from or deal with them until attitudes are changed.

You are assuming there is a negative issue with the SLB design.  Has it occured to you there may not be?  In what I've seen thus far we have zero evidence to suggest there is a negative issue in this (see the sentence below) respect.

I'm specifically refering to the fact that the SLB holds the slide further back than the stock G20 barrel.

Redline, this surface (indicated by the arrows in the pic) is what is holding your slide back. This lug is what controls the fore/aft position of the slide in lockup. It mates to the slide lock / takedown plate; if the barrel lugs don't fit the cut in the plate, it will set the slide back. Or if the lug is just too long.

Thanks for the clarification.  It's more less what I thought but wasn't sure.  Wish I new how to make arrows and stuff on photos.  Of course it's just laziness that I haven't looked into it.

Excellent considerations of food-for-thought EdMc.  Could be: none of, one of, some of, or all of, the above.

AND, we have no reason that I've come across to suggest there's a negative issue anyway.

That's a great idea.  Please fill us in on his thoughts.

[MrRedbull616]

well if that's an acceptable fit to you then I guess there is no problem.

anyone have a different model (other than 20 or 29) storm lake barrel to check fit of?

I'ld be curious to know too.  Simply because I wonder if that's a route they take only with the G20, or others too.  Especially in the more common Glock models like the G17, G19, G22, G23, G21, and G30, among others.

technically with the SLB barrels cut like this they are slightly out of battery???

So shouldn't that be a safety concern??? if not a timing issue with slide unlocking too soon???

That is sort of what I would think, held slightly out of full battery and time could be off as well because it is not in the proper place to start with.  Sorry if I opened a can of worms by trying to explain this stuff, I was trying to lead you all into looking deeper at all the angles and shapes that are associated with the barrel fit.  I had see other articles at another Glock Store site that mentioned this very same issue long ago as well.

BTW, I'll have to look at my Storm Lake barrels (2007) for my G-29  10mm and 40S&W to see if this is an issue on mine.  But they have shot well when I used them...

Just checked mine for the G-29 both SL barrels allow the slide to retrun exactly like tha factory barrel.

Keep the stock barrel. Keep it simple.

Change the recoil spring to a 20 or 22 pounder.

I wonder though, is it really out of battery at all?  This out-of-battery thing is a tad over my head even though I loosely get what it means, but my reasoning is that if the locking lugs of the barrel are fully seated in the locking block of the frame, and the barrel is fully seated in the frame at the same time, and assuming with all that that headspace is correct, then how is it out of battery in any way whatsoever?

I'm thinking of it kind of like the common saying that there's more than one way to skin a cat.  Just because slide position is changed, I'm not necessarily sure that either head space or battery position are.  In other words, does the SLB dimension that holds the slide back further than the stock G20 barrel have any bearing on what dimension of the SLB controls headspace or in/out of battery dimensions?  I'm thinking;  No.  Thoughts?
