When I was using the 209 primers in my stainless Omega they always just fell out when I opened the falling breech. In fact it is important to be sure to hold the gun up so that when the primer falls out it does not get stuck in the trigger group. I changed mine to the .25ACP conversion and the ability to handle the .25 brass easier than the 209 primer is worth all the expense besides the fact that the range of power available for primers is very wide compared with what is available in 209 primers.
