grip safety problems


February 11, 2014, 12:06 AM
I purchased an Ed Brown beavertail safety from midwayusa, model 868-1, their ad said for series 70 or 80, but when I installed it in a 9mm series 70 Colt commander the "nose"?, is too short to prevent the trigger bow from moving. There is enough movement that the pistol will fire without depressing the safety. (installation is correct, the trigger moves freely when the safety is depressed but will still moves a little when not. I relieved the underside slightly, more of a polish, so it would slide over the trigger bow but did not alter the length). I noticed on Ed Brown's website that the model I purchased is for a series 80 pistol, is this the reason it won't work? Is the part that engages the trigger bow longer on a series 70 model? I can accept that I should have researched a little more and may have purchased the wrong model, but I need o know if I purchase another for a series 70 pistol it will work. OR.... do I have another problem?
Thanks in advance for your help.

Hard to say.
The grip safety itself is the same.

But other factors such as your frame pin hole locations, trigger bow length, sear, hammer, & disconnect fit can also have an influence on the safety tab engagement.

Since you have already modified the safety, it is unlikely you can return it.

SO, I would lay the tab on a steel bench block and peen it slightly longer so it can be properly fitted to your gun.

Thanks, took your advice, preened it slightly and now works fine.

Well all right then!

Heads up for next time. Ed Brown cast parts are pretty bad. I've never used a Brown grip safety that I have liked. The parts come in warped and need to be heated and bent back into shape. Also, the beavertail section has a flaw built into the casting. The shape of the sides of the beavertail are wavy and you have to completely reshape the part to match.

Many of the thumb safeties I have received have had less than straight cross pins too.

Just a heads up for future readers. Consider other options if you can.

EB quality does seem to have slipped, but it is not the only one. I suspect that the casting houses that have been doing the casting for him and others have cut some corners. That's why EGW and Wilson have come out with bar stock machined parts. Pricey, but oh so nice with none of the worries about bent pins, warpage, or voids.

Amen BBBBill.

EGW and Wilson are paying attention to the needs of the consumer where it seems that Ed Brown is just putting out the same ol parts they have been with the exception of a couple barstock parts.

You can add Harrison & Design to the short list of very high quality parts too. Their new thumb safety is really nice.

Yep! Should have mentioned John Harrison up there, too. He's a great smith with top drawer parts.
