Mifune326 Posted December 15, 2010 Share Posted December 15, 2010 (edited) First of all, let me say I LOVE my Glocks! And I understand how Glock decided on the geometry of its frames. But I've always wondered why they chose to make their slides wide and block-like and not a little more tapered like S/A has done with their XDm series. Anyone know what the method in Glock's madness is as it relates to this? Edited December 15, 2010 by Mifune326 Link to comment Share on other sites More sharing options...
Kevin G. Posted December 15, 2010 Share Posted December 15, 2010 I would assume that the square shape didn't happen as a result of a specific planned outcome. It was more than likely the result of a lack of benefit aesthetic machining operations would bring to the product. Cost benefit analysis. The bricks do sell and operate extremely well.

Jman Posted December 15, 2010 Share Posted December 15, 2010 It's just in keeping with the frames design. A tall thin slide defeats the low bore axis advantage he achieved using the combination we have. Jim Link to comment Share on other sites More sharing options...
Mifune326 Posted December 15, 2010 Author Share Posted December 15, 2010 Ahhhh I see your point. The slide has to be more block-like to keeps its profile as low as possible. Got it.

Duane Thomas Posted December 16, 2010 Share Posted December 16, 2010 It's because of the mechanical operating system used in the gun. There are two commonly used mechanical operating systems in auto pistols, re how the barrel locks and unlocks during cycling, the internal tilt barrel (commonly called the Colt/Browning system because it was first designed by John Moses Browning and first appeared in guns produced by Colt) and the external tilt barrel (commonly called the Petter system - though it was not actually Charles Petter who first designed it). The internal tilt barrel system works through having lugs on the top of the barrel mate inside the gun with corresponding lugs inside the top of the slide. This system is seen on guns like the 1911, Browning Hi-Power, CZ-75, etc. Since both the barrel lugs and the corresponding interior of the slide are rounded, internal tilt barrel guns tend to have trim, rounded slides. The external tilt barrel system works through having the front of the barrel hood mate with the front of the ejection port. This is the system used on guns like the Glock, SIG P220-series, and HK USP and its derivatives, etc. Because, in order to work, the contact surfaces of the barrel hood and the ejection port must be squared-off, external tilt barrel guns tend to have wide, blocky slides.

twodownzero Posted December 16, 2010 Share Posted December 16, 2010 I do wonder if you're completely right, Duane. Is there any reason to believe that a rounded slide wouldn't work with the latter system you described? I understand what you mean about the locking area on the front of the barrel hood, but do you believe that the squared shape is absolutely necessary? It seems to me that the advantage of making it "blockyier" is to maximize surface area and thus the lockup area, but it doesn't seem to me that such a shape is absolutely demanded by the design.

Duane Thomas Posted December 16, 2010 Share Posted December 16, 2010 Well, if you figure out a way to make a "round external tilt barrel" gun that the gun companies haven't, let me know. The advantages of such a gun are so apparent, and so desirable, I think we can safely assume that if it was possible it would have been done by now.

Kevin G. Posted December 16, 2010 Share Posted December 16, 2010 I guess I took his question wrong. I thought he meant why couldn't they make it look slimmer and sexy or give it some type of shape other than "block". Like Smith did with the M&P and other manufacturers have done with this action type. Maybe it's like women...some guys like 'em blocky, other guys like em with more shape and some guys just don't like any of them. Link to comment Share on other sites More sharing options...

I totally understand what Duane is getting at Kev, but you're right, I was wondering why the shape of the Glock's slide was so block-like, and not a little more sexy like the M&P and XDm (while still being able to accomodate the external tilt barrel system as described by Duane).

Rob D Posted December 16, 2010 Share Posted December 16, 2010 When you're the original plastic gun that runs 100% on anything you feed it, you don't have to make you gun look schnazzy to compete. When you're coming into the market 15 years later and trying to compete with the guys who have been selling said pistols to tons of agencies and individuals for over a decade, adding some cosmetic flare to your product couldn't hurt.

kevin c Posted December 16, 2010 Share Posted December 16, 2010 How much started out as a matter of form following function, and has any of it evolved over time into aesthetics and brand recognition? Starting with a bar of steel and machining off only what is absolutely necessary gets you functionality at less cost, and mebbe that's what mattered to Herr Glock when he bid for the Austrian Army's sidearm contract. Fast forward to today: while that blocky profile may be ugly, it is also highly recognizable. The same way BMW has their characteristic front grill, Glocks have an expected visual component. Nowadays, I wouldn't be suprised to hear that some visual appeal goes into the design of gun from the outset. It may not change functionality, but it might affect marketability. Might not that be part of the difference? Glock might consider a change for marketing reasons, but might run up against resistance from their customer base, not to mention considerable retooling expense. Perhaps only small cosmetic changes would be possible (fish gill slide serrations, anyone?). 'jes speklatin' Link to comment Share on other sites More sharing options...
Kevin G. Posted December 16, 2010 Share Posted December 16, 2010 Well put kevin c. Let's not forget one of the earlier concessions to a targeted market. That stylish beveled at the front slide that was introduced with the 34, 35. Link to comment Share on other sites More sharing options...

Starting with a bar of steel and machining off only what is absolutely necessary gets you functionality at less cost, and mebbe that's what mattered to Herr Glock when he bid for the Austrian Army's sidearm contract. I agree with what you guys are saying. (With the minor added clarification that Glock slides aren't machined to shape, they're formed by bending a piece of sheet steel over a mandrel.) But the shape of the Glock slide strikes me as very much "function over form". Everything there you need, nothing you don't - and who care's what it looks like? Also I very much like the fact that Glock slides - the Glock overall, for that matter - are very "soft", i.e. there are no sharp edges anywhere to cut up the lining of a concealing garment, or cut up the shooter's hands during a fast gun manipulation. When the Glock was first introduced there were really no other guns even in its class in this area - and 25 years later still damn few that are. Actually, I'm in the minority I guess in that I find that sort of stripped-down, spartan, businesslike look very visually appealing. But I know that some people don't.

kevin c Posted December 17, 2010 Share Posted December 17, 2010 ...Glock slides aren't machined to shape, they're formed by bending a piece of sheet steel over a mandrel... Did not know that - very cool. Thank you, Good Sir, for such a juicy tidbit! Actually, I'm in the minority I guess in that I find that sort of stripped-down, spartan, businesslike look very visually appealing. But I know that some people don't. Nah. Like you, Duane, I like my Glocks pretty much as they come OOTB ('cept for sights, grip tape, and the occasional concession to my weakness for tinkering inside).

GForceLizard Posted December 20, 2010 Share Posted December 20, 2010 I was not taken with the look of Glock when I bought my first. I've come to appreciate the no nonsense all business look.

Every time I see someone clear a jam from a steel framed gun while running a stage, I appreciate the looks of my glock just a little bit more.

R-Bros_JLR Posted December 21, 2010 Share Posted December 21, 2010 Is it bad if you use one Glock as a hammer to take apart another stubborn Glock?
