(Click here for background on this litigation.)
After our lawsuit was filed, the Handgun Roster Board approved two 'integrated mechanical safety devices' that loosen restrictions for some handguns. Omega Lock is a cartridge-like device you insert into a semi-auto pistol chamber, then insert a wrench through the muzzle and tighten the lock to wedge it in your chamber.
In practice it appears to be a potentially unsafe system but at least serves as a 'legality lock', in that its sale allows a dealer to sell some semiautos which might not be available otherwise. A GSI magazine lock was approved too. It fits only a small number of semi-autos, but again serves as a legality lock, and like Omega you can simply not use it after you buy the gun. (The GSI was made famous in 2000 by Governor Glendening in his failed televised demonstration of how easy these safety devices are.)
Any technical drawbacks of these products aside, we applaud anything that makes more handgun products available to honest gun owners even if at needlessly increased price. Because it is unclear how long anti-gunners will allow these gizmos to serve as IMSDs, our advice is: if you want a semi-auto that one of these legality locks fits, buy it while you can. Our suit would have the effect of giving much broader relief, but Ehrlich's MSP is fighting us hard and even if we are successful we won't know for months.
