The TM45 is lighter than full metal pistols, One of the biggest improvements over the universal service pistol series is the ambidextrous slide stop, making it a great for left handed shooters. The slide has a sleeker look than the USP with rounded edges on the slide and a tapered front end, minimising snagging on holsters and clothing. The safety lever also doubles as a decocker; pushing down on the lever safely drops the hammer. Metal parts include the safety lever, slide locks, trigger and trigger bar, hammer, internal frame, magazine, recoil rod and hop-up unit. The Green gas magazine holds 26 rounds, A 20mm lower accessory rail is built into the lower frame. The trigger guard is made wider like on the universal service pistol to allow the shooter to wear gloves. The adjustable hop-up is located inside the ejection port and can be adjusted without having to remove the slide.
