i like the Vickers for my gen 3's and for my gen 4's i now have switched them all to the Crux Ord mag release.

the Crux ord is slightly extended but more round and easier for me to depress than stock.

Agree with Bruce totally the marginal gain in reloading speed is negated by any risk of losing the mag. Even with a 6-7 shot gun the chance of needing a speed reload in a defensive encounter is very very slim
