I just tested the new Mod. Great work. 
I collected some infos from my experience if you need that for something:
1. The "Mustang 44" needs it Scope, same goes for "Deutsche M95", "Mustang MAR4", basically all weapons with a scope.
2. "Frinesi Shotgun" and "Frinesi Auto" needs a louder Shoot Sound.
3. "Meyer TMP (P5)" is just a not as good as it´s "Meyer TMP". Maybe it´s the sound, i don´t know.
4. "Koffler KSS" is just an overall bad experience, sound- and lookwise.
5. "MB POW90" doesn´t sound correct when shooting automatic, single sounds right.
6. "AR36 Sniper" Weapon Model seems to be not correctly ripped.
7. "RL 22" needs it´s correct Reloading Animation.
8. I don´t know why, but i expected when that the alternate Mode of the "Wolfram P2K" would be that it´s the silenced Version. Having the animation where the Character put the Silencer on it like in the Game would be cool.
9. I think the "Raptor Magnum" has a Laser as second Mode.
11. The "Impact Grenade" was actually the strongest weapon in "TWINE". It really needs it´s distinct Beeping Sound and have to explode when Enemies got near them, and not when throwing the Grenade. In case you don´t remember, i found a Video in
which this Grenade get used: https://youtu.be/1nW5zf7misQ?t=106
By the way, i have all the Sounds in Wave Format from this Game. Someone uploaded that on the ZDoom Forums long ago. But in case you need it, here it is: https://www.mediafire.com/file/9ydxi8kw89ogaxo/007sounds.zip/file
Please see this all as an feedback. 
Thanks for the feedback. I will see what I can do by the next version.
EDIT: V1.6 Has been released. Not much, just some changes, one of which is big enough.
These hotfixes are from V1.5.1 which I released as a holdover for this Version:
Frinesi Shotgun and Frinesi Auto's firing sounds should now be louder.
Fixed the Frinesi Shotgun's Ammo Pickups using the wrong sprite.
Seamaster Speargun and Delta 900 Mag can now auto-fire again.
And for the real deal....
Koffler KSS no longer goes into parts of the put away animation after reloading it. hopefully it should be better.
Wolfram P2K can now finally be fitted with a silencer. This removes the need to have the silenced version as a standalone weapon.
Finally added the 'BRIGHT' flag to nearly all of the weapons.
Picking up The Frinesi Special 12 Speedloader Upgrade now gives you the gun itself if you haven't already. It's also more likely to spawn, too.
All three Grenades now have low throw range, and for the Flag and Cluster Grenades, are now more unlikely to bounce around like crazy.
Fixed most of the weapons's alt fires still using ammo even when Unlimited Ammo is on.
Wolfram P2K (PS) can now drop from the Shotgun Spawner.
And if you didn't know already, I got more addons up for download as well: Auto-Taunts, Music Pack, N64 Weapon Set Only, PS Weapon Set Only and Prototype Weapons.
