What is the difference in these two pistols?

Is the grip different or the length of the dust shroud or ??

The grip is shorter, front to back, in the SF model. Someone had a pic showing the difference...basically think of it this way, in the SF model the open channel in the backstrap is smaller.

3mm less from backstrap to trigger on the SF

Doesn't the 30SF have a light rail where the 30 does NOT?? Could be wrong here...I had a 30SF and it had one.

Depends on the generation both my 30 and 30SF have the glock rail

Do they use the same mag?

Yes, and both accept G21 magazines as well.

yes, this exactly. i know it does not sound like much, but don't be fooled by the small reduction. i have rather large hands and my 21SF feels amazing in my hand. i also have a standard 21, which feels like a brick compared to my SF model. i shoot both well, but the SF just feels so much better. i could only imagine this same idea would apply to the 30 vs. 30SF.

I bought a 21SF on Sunday.  I couldn't believe how much better the SF version felt in my hands compared to the regular 21.  The only reason I didn't buy a 30SF they were out of stock.  I will get one eventually.

Hi.  Does anyone know of the "mag sleeve" that goes on the G21 magazine that will allow it to fit snug in the 30SF?  Saw one advertised once, but cannot find it now.




Thanks

The SF stands for "Sausage Fingers" which is what I have and the 30SF is a great fit.  Not ideal but for a 45 (especially double stack) it is awesome.
