It happened once or twice during dry fire. Usually it only occurs when Iam realy tensed. But I can´t reproduce it intentionally.
Does the original mag release fit in the shadow frame? If so, I replace the shadow extended mag release. Unfortunately Iam living in germany...so thank you for your offer...but I don´t think, that it will be a good deal for both of us. :-D
I have very short fingers - but I also don´t see the need of a extended mag release.
