Glock 20/29---Reg vs SF model

[SteveO666]

Looking at the 10mm Glocks and considering picking one up but I am a little confused.

There is the G20 and G29 Model is both Standard and SF models. When I look at the Glock site they list the width as 32.50mm regardless of Model.
Is the site wrong or is there really no difference in Width? If no Difference what does the SF mean?

Thank you,

I'm no glock expert as I admit I really dislike glock. The G20 and 29 will be the same width because you can use a G20 mag in a G29.

I believe the SF models (I own a Gen 3 SF G21 that I converted to 10mm due to cost and to ensure I have a supported chamber I bought aftermarket Storm Lake barrel) difference is the back strap...kinda like on the latest Gen 4 with the removable rear grips.

I'm sure someone with more glock knowledge will come along.

short frame. pre interchangeable backstraps

I believe the "SF" designations are for gen 3's but the gen 4's do not have an "SF" option as they have interchangeable backstraps. Think of the gen 3 Glock 20 SF as a Glock 20 gen 3 and 1/2. I have a SF gen 3 Glock 20 but am no expert. This is what I remember when purchasing a few years ago and looking into this myself.

100% correct.

If I remember correctly, the SF is smaller from the front of the grip to the back. Width is still the same. I have a G20, and after feeling a G20SF, I wish I would of went SF

I think the backstrap is reduced on the SF models, thus creating a shorter distance to the face of the trigger. The Gen 4's without backstrap in place is the Gen 3 SF dimension I was told at Glock armorers course. Guy could have been full of BS for all I know, but it sorta makes sense. Anyone verify that?

The backstrap answer makes sense. Thanks for clarifying.

Curious if this can be verified as well...

Of course now that I read the Actual Description (and the post above) I have my answer(Doh'). I found this in the description of the G20 SF:
"The SF model reduces the circumference of the receiver at the rear, or "backstrap," offering increased comfort and control—especially to shooters with smaller hands."
This was the same on every other SF model as well.
This is the Notation on the GEN 4 version of the G21
"The Modular Back Strap design on the G21 Gen4 lets you instantly customize its grip to adapt to an individual shooter's hand size"
G20 Gen 4 States:
"The Gen4 edition now incorporates a wider selection of grip dimensions to make customizing your grip even more precise."

So I think that the statements made by others regarding the Interchangeable Backstrap on the GEN 4 Models vs the GEN 3 SF models are accurate.
