Description
The Samson Vertical Grip in the Long grenade style is the biggest of the bunch, giving you a full 4.20 inches of real estate to wrap your hand around. If you've got larger hands or you just like a grip you can bury your whole fist into, this is the one to reach for. It's built from 6061-T6 aluminum with a steel rod running through the core, so there's real substance to it. The finish is a Type III hardcoat black anodizing that shrugs off holster wear, weather, and the general beating a range gun takes over the years.
The grenade texture is the star here. That aggressive pineapple pattern wraps the whole body and locks into your palm whether you're running a full grip or choking up with a couple fingers over the handrail. Folks who've run these note the knurling gives a confident hold even with gloves or sweaty hands, and the aluminum body helps keep things comfortable when a suppressed barrel starts heating up the handguard.
What Makes the Grenade Long Vertical Grip Different
The two-piece design is the feature people end up appreciating most. The M-LOK attachment lug stays bolted to your rail, and the grip itself threads on and off that lug. That means you can pull the grip for storage or a case without losing your mounting position, and swap it between builds if you set them up the same way. Installation is straightforward with the included hardware, and once it's torqued down it doesn't budge.
Storage Built Into the Samson Grenade Grip
There's a hollow interior behind the removable aluminum bottom cap, which is handy for tucking away a spare battery, small cleaning tools, lube, or anything else you want to keep on the gun instead of rattling around your bag. It's a small touch, but it earns its keep on a truck gun or a rifle you take to class.
Samson has been machining firearm parts in New Hampshire since the mid-90s, and these grips have a well-earned reputation for lasting. Owners regularly report running the same one for years across multiple platforms without it showing wear. It's a fitting match for AR-15s, PCCs, and just about any M-LOK-equipped rifle or pistol.

Frequently Asked Questions
How long is the Grenade Long vertical grip compared to the other sizes?
The Long version measures 4.20 inches, making it the tallest grip in Samson's grenade lineup. The medium comes in around 3.50 inches and the short is roughly 2.125 inches. Go with the Long if you have bigger hands or prefer to wrap your entire fist around the grip.
Will this fit my M-LOK handguard, and does it need more than one slot?
It mounts to any standard M-LOK attachment point. The grip is designed to fit into a single M-LOK slot or bridge across two slots depending on your rail, so it works on most AR-15, PCC, and other M-LOK-equipped handguards. All the hardware you need to install it comes in the box.
What does the two-piece design on the Samson grenade grip actually do?
The attachment lug bolts to your rail and stays there, while the grip itself threads onto that lug. This lets you remove the grip for storage or transport without losing your mounting spot, then reattach it in the same position. It's a nice touch if you break your rifle down for a case or move the grip between builds.
Is there really storage inside this vertical grip?
Yes. The body is hollow and the aluminum bottom cap unscrews to give you room for small items like a spare battery, lube, or compact cleaning tools. It's a practical spot to stash range essentials right on the gun.
