BudsGunShop.com - 19rd mag vs 15rd mag

they make 2 different P10 mags the full size has the same bot as the P09 mag the compact is a shorter 15 round mag to fit the shorter p10C grip (the P10 full size mag will also fit the compact gun but will extend below the grip)

Michael, there are 2 flavors of P10 15rd magazines (Compact 15rd and Full Size 15rd). Both can be seen here : https://gunmagwarehouse.com/brands/cz-usa -------------- This (Full Size Magazine Fits: - CZ P-10 F Full Size Models (Reversible Magazine Release Compatible) and CZ P-09 Full Size Models.

There's a website called handgun hero that let's you compare features and measurements side to side on most major handguns. Went on there and compared the P10F and the P10C and the P10F has a height of 5.5" where as the P10C has a height of 5.2" but if you look at the picture comparison it looks like the part of the grip where the mag sits is even closer in size then that. The biggest difference in size on these two pistols seems to be slide length.

It's like the vp9/p30 for years had a 15+1 cap then they released a 17 round mag that is the exact same length so looks like CZ probably designed the compact with a smaller capacity to keep the weight down and the grip size sont really all that different.
