I've been admiring the massive Walker pistols, and have been pretty impressed with the power they produce. However it hasn't escaped me that the loading lever has a habit of dropping down due to recoil. It seems like a simple "fix". And for those not necessarily concerned about historical accuracy, and prefer to focus on functionaliy, a rod catch like the 1860 Army has would seem to be a no brainer. Has anyone tried this? I've seen the filing of the retention spring mentioned in numerous videos, but it doesnt really seem to be very effective.
