Will Gen 5 Glock Magazines Fit Gen 4 Pistols? The Definitive Answer
The question of Glock magazine compatibility between generations is a common one, especially for those considering upgrading or expanding their collection. So, will Gen 5 Glock magazines fit Gen 4 pistols? The short answer is yes, but with a caveat.
While both Gen 4 and Gen 5 Glocks share a significant degree of interchangeability, there's a subtle difference that needs addressing. Let's break it down:
The Compatibility Issue: A Minor Design Difference
The primary difference lies in the magazine's floorplate. Gen 5 Glock magazines feature a slightly redesigned floorplate, often described as being more streamlined or having a more aggressive texture. This change, while minor, can affect the fit in some Gen 4 pistols.
Functioning with Gen 4: The Reality Check
In the vast majority of cases, Gen 5 magazines will function flawlessly in Gen 4 Glock pistols. You'll likely experience smooth feeding, reliable ejection, and consistent performance. The difference in the floorplate is usually insignificant enough to not cause any issues. Many users have reported using Gen 5 mags in their Gen 4 pistols without incident.
Potential Exceptions and Things to Consider:
- Aftermarket Modifications: If your Gen 4 pistol has any aftermarket modifications, especially to the magazine well, compatibility could be affected. These modifications might create interference with the slightly different Gen 5 floorplate.
- Individual Variation: While rare, there might be slight variations in manufacturing tolerances across different pistols or magazines. This could lead to a slightly tighter fit or even a potential for malfunction in extreme edge cases. If you notice any unusual resistance or difficulty during insertion, consult a qualified gunsmith.
- High-Round Count Magazines: Extremely high capacity aftermarket magazines (beyond standard factory capacity) might show a more pronounced incompatibility issue, especially if they incorporate other design changes beyond the floorplate.
Summary: A Safe Bet, but with Due Diligence
In conclusion, using Gen 5 Glock magazines in Gen 4 Glock pistols is generally safe and reliable. The slight design difference in the floorplate is usually not a significant factor. However, always exercise caution and be aware of any potential aftermarket modifications to your firearm that could affect compatibility. If you experience any difficulties or malfunctions, immediately cease use and seek professional assistance.
