The trigger frame is adapted to have a trigger assembly mounted thereto. The system further comprises a grip frame having an elongated channel and a hand grip extending downwardly from the elongated channel. The trigger frame is removably mounted in the elongated channel of the grip frame. The accessory rail of the trigger frame is positioned forward of a forward end of the elongated channel of the grip frame so as to be exposed. The system further comprises a slide and barrel assembly slidably mounted on the slide rails of the trigger frame. ## Claims ### Claim 1 A modular handgun system comprising: an elongated universal trigger frame having a barrel locking block, a pair of slide rails, and an accessory rail, said trigger frame adapted to have a trigger assembly mounted thereto, a grip frame having an elongated channel, a hand grip extending downwardly from said elongated channel, and a trigger guard extending between said elongated channel and said hand grip, said trigger frame removably mounted in said elongated channel of said grip frame, said accessory rail of said trigger frame being positioned forward of a forward end of said elongated channel of said grip frame so as to be exposed, and a slide and barrel assembly slidably mounted on said slide rails of said trigger frame. ### Claim 2 (depends on 1) The handgun system of claim 1 including at least two said grip frames and at least two said slide and barrel assemblies, one of said two grip frames having a first hand grip length and the other of said two grip frames having a second hand grip length, said second hand grip length being longer than said first hand grip length, one of said two slide and barrel assemblies having a first slide and barrel length and the other of said two slide and barrel assemblies having a second slide and barrel length, said second slide and barrel length being longer than said first slide and barrel length. ### Claim 3 (depends on 1) The handgun system of claim 1 including at least first, second, third, and fourth said grip frames and at least two said slide and barrel assemblies, said first grip frame having a first hand grip length and a first hand grip circumference, said second grip frame having a second hand grip length and a second hand grip circumference, said second hand grip length being longer than said first hand grip length, said third grip frame having a third hand grip length and a third hand grip circumference, said fourth grip frame having a fourth hand grip length and a fourth hand grip circumference, said fourth hand grip circumference being greater than said third hand grip circumference, one of said two slide and barrel assemblies having a first slide and barrel length and the other of said two slide and barrel assemblies having a second slide and barrel length, said second slide and barrel length being longer than said first slide and barrel length. ### Claim 4 (depends on 1) The handgun system of claim 1 wherein a reward portion of said trigger frame has a first rearward extension, said grip frame has a first recess which receives said first rearward extension, said trigger frame and said grip frame have alignable openings, and further including a pin removably inserted in said openings once aligned. ### Claim 5 (depends on 4) The handgun system of claim 4 wherein said rearward portion of said trigger frame further has a second rearward extension spaced below said first rearward extension, and said grip frame has a second recess which receives said second rearward extension. ### Claim 6 (depends on 5) The handgun system of claim 5 wherein said second rearward extension comprises a pair of transversely spaced apart rearward hooks. ### Claim 7 (depends on 1) The handgun system of claim 1 wherein said trigger frame is adapted to have a slide release lever mounted thereto and a slide takedown lever mounted thereto. ### Claim 8 (depends on 1) The handgun system of claim 1 wherein said trigger frame is fabricated of a metallic material and said grip frame is fabricated of a polymer material, and wherein said trigger frame is a unitary structure with said barrel locking block, said pair of slide rails, and said accessory rail being formed integrally therewith. ### Claim 9 (depends on 8) The handgun system of claim 8 wherein said trigger frame is machined from a single billet of metallic material. ### Claim 10 A modular handgun system comprising: an elongated universal trigger frame having a barrel locking block, a pair of slide rails, and an accessory rail, said trigger frame adapted to have a trigger assembly mounted thereto, a grip frame having an elongated channel and a hand grip extending downwardly from said elongated channel, said trigger frame removably mounted in said elongated channel of said grip frame, said accessory rail of said trigger frame being positioned forward of a forward end of said elongated channel of said grip frame so as to be exposed, and a slide and barrel assembly slidably mounted on said slide rails of said trigger frame, wherein a reward portion of said trigger frame has a first rearward extension, said grip frame has a first recess which receives said first rearward extension, said trigger frame and said grip frame have alienable openings, and further including a pin removably inserted in said openings once aligned, wherein said trigger frame and said grip frame have cooperating ramp surfaces for camming said trigger frame rearwardly relative to said grip frame after said first rearward extension has been inserted into said first recess and as said trigger frame is pivoted downwardly into said channel of said grip frame. ### Claim 11 A modular handgun system comprising: an elongated universal trigger frame having a barrel locking block, a pair of slide rails, and an accessory rail, said trigger frame adapted to have a trigger assembly mounted thereto, a grip frame having an elongated channel and a hand grip extending downwardly from said elongated channel, said trigger frame removably mounted in said elongated channel of said grip frame, said accessory rail of said trigger frame being positioned forward of a forward end of said elongated channel of said grip frame so as to be exposed, and a slide and barrel assembly slidably mounted on said slide rails of said trigger frame, wherein a reward portion of said trigger frame has a first rearward extension, said grip frame has a first recess which receives said first rearward extension, said trigger frame and said grip frame have alienable openings, and further including a pin removably inserted in said openings once aligned, wherein said trigger frame has an outwardly extending lug on each lateral side thereof and said channel of said grip frame has a notch in each lateral side thereof, each said lug being received in a respective one of said notches. ### Claim 12 A modular handgun system comprising: an elongated universal trigger frame having a barrel locking block, a pair of slide rails, and an accessory rail, said trigger frame adapted to have a trigger assembly mounted thereto, a grip frame having an elongated channel and a hand grip extending downwardly from said elongated channel, said trigger frame removably mounted in said elongated channel of said grip frame, said accessory rail of said trigger frame being positioned forward of a forward end of said
