I like my FNP .45 ACP a lot. It HAS a replacable backstrap for adjusting the grip. I have short fingers so I run the thinner backstrap on mine. In the lockable case that the pistol comes in is a thicker backstrap for folks with longer fingers. It is a matter of about 60 seconds to change them out. Just stick a paper clip in the little hole on the strap and it trips a latch that secures the backstrap to the pistol. Slide one off and slide the other on until it clicks. It locks in solid with no problems. The FNP.45 also comes with THREE magazines. I have the GOV model that has one 15 rd. mag and two 14 rd. mags. I swapped some 20 yr. old sks ammo at a gun show for two more new 15 rd. factory mags. The case also comes with a lock ,owners manual and shell case when it was tested. I also have two shooters paks. A few models come with them. A shooters pak has a BLADE TECH holster,mag holder for two mags,and a yellow training barrel for acadamy classes or classroom carry of the pistol. I have one pak set up pancake style and the other set up with belt loops. The FNP .45 ACP is the best handgun I have ever owned. My friend and I both have hand held NV scopes and practice night fire on his 56 acre farm. It is a situation where we set up targets at night,hold the scope in one hand and fire the FNP with our right hand. We both have lasers on our pistols and it is easy to find the sillouet target with the NV scope,place the laser dot on the target and try to put 15 rds. in the ten ring. The FNP.45 has a rail on the dust cover under the barrel for mounting lasers or lights. A decent NV scope can be found at the Harbor Freight stores on sale for about $50. A decent laser can be had nowadays for less than $100. BTW I am from the old school. I would not give you two cents for a handgun without a hammer. I despise Glocks. I think people are crazy for buying a DA handgun without a hammer and a twelve pound trigger pull instead of a DA/SA handgun. I just don't get the Glockcrap. People act like they have been bitten by Zombies when it come to some of these handguns with the gimmicks. They fail to see that their life is on the line when it comes to using one of these pistols in a back alley or dark parking lot.
