Factory Glock 23 – 13 Round Magazine

Note:

Glock Magazines Can Be Very Difficult to Load When New. Often the Last Round Will Not Fit Until the Magazine Has Undergone a Break-in Period. It is Recommended That the Magazine Be Loaded With All but the Last Round and Left for a Few Days to Compress the Spring. Cycling the Magazine From Full to Empty Multiple Times Can Assist in the Break-in Period.
