Designed for Gen 4 Glock Pistols with MBS Backstraps
Gen 4 Glock pistols introduced the Modular Back Strap (MBS) system, allowing shooters to customize grip size and feel. The Trigger Housing Pin MBS (Part #7416) is engineered specifically to work with that system:
Extra length (1.020") to pass through the frame and the installed backstrap
Provides a secure hold so your backstrap doesn’t shift or loosen under recoil
Maintains proper alignment of the trigger housing unit inside the frame
If you’ve added or swapped backstraps, or your original long pin is lost or damaged, this is the proper OEM replacement.
Genuine Glock OEM Quality and Fit
Because this is a factory Glock part, you get:
Exact dimensions and tolerances designed for Gen 4 frames
Perfect compatibility with Glock’s trigger housing, frame, and MBS backstraps
The same part you would find in a factory-built Gen 4 with backstrap installed
Using genuine Glock parts is the best way to preserve the reliability, safety, and resale value of your pistol. Unlike off-brand pins, this OEM 7416 pin is matched to Glock’s internal specs and materials.
Key Features & Benefits
1. Extended 1.020" Length for MBS Use

Lock everything together without flex or wiggle
Prevent backstrap movement during recoil and hard training
If your backstrap doesn’t feel solid—or your original long pin went missing—this is the exact replacement you need.
2. Compatible with All Gen 4 Models with Straps (and G37 Gen 4)
According to multiple product listings, the Trigger Housing Pin MBS 7416 fits:
That makes this part ideal for maintaining or upgrading:
Full-size, compact, and subcompact Gen 4 frames that use removable backstraps
Agency or department Gen 4 duty guns set up with MBS grips
Always verify fit with your specific model, but if you’re running a Gen 4 with backstrap, this is the long trigger housing pin you’re looking for.
3. Robust Construction for Hard Use
As an OEM Glock component, the Trigger Housing Pin MBS is built to endure:
Thousands of rounds and repeated recoil cycles
Routine disassembly for cleaning and maintenance
Daily carry, duty use, and training environments
The pin works in conjunction with your frame and internal components to maintain correct alignment of the trigger housing, helping preserve the Glock reputation for toughness and reliability.
4. Ideal for Maintenance, Rebuilds, and Armorers
This part is essential for:
Armorer benches and parts kits – keep spare pins on hand for Gen 4 fleets
Rebuild and refresh projects where older frames are being serviced
Custom grip setups where backstraps are frequently changed
Replacing lost or damaged pins after backstrap or trigger housing work
At a low cost and with high importance in the frame assembly, the MBS Trigger Housing Pin 7416 is one of those small parts that’s cheap insurance for long-term reliability.
