SIM-X Defense Core 9mm Luger, 45 grain hollow point. A very light, very fast polymer core defensive round.
Who it’s for
9mm owners interested in an unconventional defensive load with low recoil. SIM-X pairs a lead free synthetic polymer core with a hollow point jacket. The maker lists it at about 2,250 fps, far faster than a typical 9mm hollow point, from a bullet weighing a fraction as much.
Lighter recoil can make faster follow up shots easier, which is part of the appeal.
What you get
- 45 grain hollow point
- Lead free polymer core
- About 2,250 fps, per the maker
- Low felt recoil
Specs
Caliber 9mm Luger. Bullet 45 grain Defense Core HP. About 2,250 fps (maker’s figure).
Light and fast gives up penetration
A 45 grain bullet has very little momentum, and light, fast bullets tend to penetrate less than conventional defensive loads. Before carrying it, look for independent gel testing, and run enough through your own pistol to be sure it feeds and cycles every time.
This ammunition ships straight to your door wherever state and local law allows.
