I have a cz75b and a p 10 F ,the 75 is fantastic at the range or on my bedside table but too heavy for concealed carry. The p10 F shoots great and comfortable to carry but hard to conceal in the summer. For all day carry in the summer I use my Glock 23 in .40 cal. Hasn't failed me yet. And I can shoot a great pattern at 10 yards,consistently with it. I own Sigs,CZs,H&Ks,Walthers and Glocks love them all.
