[Thunderbolt]

I've owned an XD 40 great weapon.The only thing is I don't like the XD grip.When I decided I "needed" a .45 I chose the 21 SF over the XD,Smith.Been very happy with my decision.Also you'll find accessories for the Glock a little easier and more plentiful to obtain.Regular model 21 mags will fit it.you will have to order holsters for Glock 29 to fit it,Holsters for the model 21 wil not fit the SF.
