Excellent Product.
Easy, fast and the fit of my Beretta APX pistol to the "type B" Insert Block was perfect.
I only used one of the padding pieces, with 3.75mm. It was not necessary to use anything else.
Drawing is easy, fast and light, as well as holstering the weapon.
I was so (positively) surprised with the result and with the product, that I already ordered the Insert Block "type A", to be used with my Walther Q5 Match (Steel Frame) Champion pistol.
Now, I'm going to use the same holster, for two different guns (the Beretta and the Walther), just changing the Insert Blocks.
Congratulations.
