Congrats! Old Santa was good this year!
That is a great gift! You must have a great husband! Obviously he is sensitive to what you really like! Better keep him around! Have a great time with it as I am sure you will! I am with Quentin on the Magazine Extensions. I can not stand to have my pinky finger hanging over the grip on any pistol. Being a lady you may not have that problem? A Lot of the magazine extensions also add another round in the mag which is by itself a good reason to install one. I have one on my Glock Model 27 40cal. which is the same pistol you have only in 40 cal.
Have a great time with your new Christmas Present! Send us a range report when you get it on the range!
